The Best Cortez pearls of all: 2008-2015

I take off this week by continuing were last I left my blog entry…in an engagingly erotochromic post about the most beautiful Cortez Cultured Pearls of All times!

And we are going to start with the pearl that I personally believe is the MOST BEAUTIFUL CORTEZ CULTURED PEARL that we have ever produced from this farm. And this pearl was produced from the…

2008 Pearl Harvest

Before I tell you about this amazingly, stunningly beautiful pearl I will recount you of hurricane “Julio”, one of the fiercest hurricanes to have hit Guaymas. But fortunately this damage was done after we had harvested our pearls.

This particular pearl is prominently featured in our original “Sea of Cortez Pearl Video” and appeared several times in a thread over at the forum. It was part of a group of drop shaped pearls that I fondly called the “Drop Dead Gorgeous Pearls”.

This particular beauty had a striking luster to it -all-natural as expected- and at its base it had a very dark purple blue color that started changing into a rainbow of colors until the very tip became a beautiful lavender-pink color, and features amazing overtones. The pearl measures 9.5 mm at its widest and the colors are absolutely EROTOCHROMIC.Drop Dead Gorgeous Pearls (7)

I was truly happy to sell this particular pearl to a very good pair of “pearly foster parents” that live in Tel Aviv, Israel. The Holy Land…to me this had a special meaning and over the years this couple became one of my dearest friends. Nora had the pearl set into a pendant-pearl enhancer to use with her Akoya pearl necklace for a very beautiful and striking piece.

The pearl is named “Epyolotli” which is the Nahuatl (Aztec) word for “Pearl” and it means “Heart of the Pearl Oyster”. I really like this name.

2009 Harvest

Then, a year later we also had more splendid pearls…not a single pearl that was equal to Nora’s 2008 pearl but that year was marked by larger than usual pearls.

2009’s largest and most beautiful pearl was sold to one of our US based buyers and I called it “La Bella” or “The Beautiful”: a lustrous, shiny 12 mm near-round pearl with a dark-green body color and a vibrant violet color.

Here you can see “La Bella” next to other gem grade Cortez pearls of around 10 mm in diameter.

That particular year we barely avoided the farm’s destruction by the disastrous effects of hurricane “Jimena”, which destroyed much of our State’s infrastructure . Guaymas was ravaged by it, so I may not have talked much about this particular pearl. Too much going on.

2010 Harvest

This was –for most Mexicans I believe- a year of shadows and lights: this year marked the 100th anniversary of the Mexican Revolution and 200th anniversary of our Independence from Spain, so it was supposed to be a year of celebrations…but we were in trapped in a terrible economic recession and in the midst of violence –in some parts of our country, but not really around our area- due to the drug trafficking cartels.

But while trapped under conditions we could not help improve (we could neither issue moral fiber –nor brain matter- to our so called leaders) we kept doing what we believe in: growing beautiful and sustainable Cortez Pearls. That year’s harvest was really good and we had one particular pearl that I named as “Matrioshka”, a unique Russian doll-shaped dark purple pearl with beautiful green overtones.

2010 Harvest 008

I simply loved this pearl and its name just came out of my mouth when I took it out of it’s mother oyster. Measuring at around 10.5 mm it was purchased by my very good friends Jeremy (CEO of Pearl and Hisano Shepherd, who had the pearl fitted into a lovely and colorful design made by Hisano. I was so happy to see this amazing pearl become a work of art! The chain actually paid the pearl a fitting homage by also having its contour. Lovely piece isn’t it???


2011 Harvest

The year 2011 was yet another challenging year. I actually don’t want to even talk about some of the things that happened, but I also mark this year as the beginning of my “personal awakening”,  so it was kind of waking up from a terrible nightmare and seeing the light at the end of the tunnel.  One must really be grateful for the “bad times” since they actually build up your character and allow you to become a better version of yourself.

2011’s best pearl was an incredibly erotochromic pearl. A chunky baroque pearl that was so dramatically different that it was like watching a person with a dual personality.

On one of its sides it was a beautiful cyan-true blue color and on its other side it had the same blue with golden and bright violet.

This pearl was purchased at the 2011 Pearl Ruckus by my friend Cathy. I don’t know if she gave this pearl a name but I had called it “Chunky”…I know! Not a glamorous name for a beautiful pearl but to me this name is really special…a pet name of sorts for someone I love.

2012 Harvest

Our worries were definitively not over. This year I fell ill and I was unable to photograph much of the pearls from this harvest. I don’t even recall a personal favorite pearl at all!

Probably the most relevant photo I have is of a group of light colored pearls with a much more colorful pearl. But the photo is simply too bad, totally missing its focus from the beautiful blue pearl in the group.

The Group

But life carries on and on…the next year I saw a major improvement in my health. I truly thank God for allowing me to continue walking on this beautiful blue planet of ours.

Harvest 2013 – Down Under!

The year 2013 was marked by a good harvest: large and colorful pearls with high Chroma. And that year was also marked by having some of the best pearls shipped all the way to Adelaide, Australia.

HighChroma HQ Barroques (1)

This lovely trio of pearls went to a my dear friend: Dyann Smith. And she has great taste in pearls! So, it was fitting to have these incredibly colorful pearls.

You can see some of “Raw Pearls” beautiful Cortez Pearl jewelry line if you visit their site.  I never had the chance to name the pearls…they just left so suddenly.

2014 Harvest

Last year’s harvest was the most abundant ever, reaching 5 kilos of Cortez Pearls. We also had some amazingly colorful pearls and also…who can forget the largest Cortez Cultured Pearl ever?!?!?!? Even if this large pearl was not the prettiest it was definitively out-of-the-ordinary. Here you can see “The Hulk” next to 4 smaller pearls (10, 9 and 8.5 mm) and it just looks Huge!

Perla Gigante 2014 y de 9mm

I named this pearl “the Hulk” due to its purple-green coloration and large size, but for a fleeting moment I considered the name “Barney” (yes, I believe I still suffer from the time spent watching the toddler’s TV program with my children…years go).  Decided to go all out on “The Hulk” since it just sounds more butch than “Barney”.

Specs: Baroque shaped, 17.1 mm in diameter, low luster B+ grade pearl.

Harvest 2015

Now, nearing the end of this story I can try to express some feelings I may have regarding these two posts: it has been over two decades of growing Cortez cultured pearls in the rich waters of the Gulf of California. It has been a story of both beauty and challenges so in essence it is Life itself for us.

For me each pearl harvest reminds me of certain periods of my life and I can re-live and feel the excitement of the “research days” when everything was new and we were making “pearl history”, I can also retell the pain of the “bad years” and –finally- also experience the calmness of my more “experienced years”.  Each one of these pearls in itself retells my personal story, just like a photograph reminds you of certain events and how you looked and felt like.

So, what do I want to say with this? That “Pearls are Like a Snapshot of a Person during a given moment of their Life”… Pearls are Your Personal History: the good, the bad and the experience you gain during life.  I don’t know if any other gemstone is the same, but for me this is True.

So now I finish up with the way all of this began, with a beautiful erotochromic pearl that will soon depart to its new proud owner in the United States…it has been named “Flamingo Silk” by its new owner, Nancy A.

Closing Remarks

I hope you have enjoyed this walk through memory lane and I thank you for listening a bit about my personal story…using my naturally colorful Cortez Pearls as stepping stones.

Until next time.

The Best Cortez pearls of All: 1995-2007

Just a couple of days ago I published a photo of a single pearl…but not just of any kind of pearl, but rather of THE BEST PEARL OF 2015 and this beautiful bicolored pearl had a major impact amongst those that follow me on Twitter (@DouglasMcLaurin) and Facebook: in just a couple of days it was seen and shared by about 7 thousand people.

And this made me think back and remember certain pearls of previous pearl harvests that have been just as beautiful and colorful and that I call “Erotochromic”. Of course, they are always unique and different in their beauty. At that moment I told myself: “I have never reported those pearls like I have done this year and there might be more people that could find this information interesting”.

And so I told myself: I have to make a blog post to show others these very special and “erotochromic” pearls that we have been harvesting for many years. Unfortunately it was not until 2007 when I finally had a good enough digital camera to shoot photos, and this ultimately means I do not have good photos of all these amazing pearls and some simply will reside in my memory.

So here goes part 1 of these Special Erotochromic Cortez Pearl Collection.

“Pinky” – 1995

Let me start with a bit of history: back in 1995 we were already producing our first experimental cultured pearls using our “Rainbow Lip Oyster” or Pteria sterna. I had this small group of 32 oysters and I was lucky enough to produce several pearls from these and there was this particular pearl…oval shaped and just 7 mm in diameter (those days our beads were very small (5 mm). I called it “Pinky” because of its delicate violet overtone…and my particular fondness for “Pink Floyd”.

I consider this petite beauty as our 1st Gem Pearl and I am proud to be its “dad” and not having sold it. “Pinky” is being exhibited at our jewelry store & Pearl Farm in Guaymas, Sonora, Mexico and its value transcends its mere economic value: this is the 1ST GEM PEARL produced in Mexico and Latin America and –if we just consider Marine Pearls, as opposed to Freshwater pearls- “Pinky” is also the 1st CULTURED GEM GRADE PEARL GROWN IN THE AMERICAN CONTINENT.


Harvest of 2000

Back in the day we had no idea of “christening” our pearls with a name of their own. We had –of course- heard of famous pearls that had a unique name (“La Peregrina”, “The Big Lemmon”, “Hope Pearl”, etc.) but this was an idea we had yet to fully mature into action, but we already had “Pinky” and “Bebé” (“Baby” this one I will leave for another story…a sad one) with their unique names.

That year we officially had our 1st COMMERCIAL PEARL HARVEST and it was also the year we had our “Perlas del Mar de Cortez” trademark and Logo. That year we had several amazing pearls but I remember these two:

Perlas2 Hi-Res copy

These round pearls barely exceeded 8 mm and 8.8 mm, one was violet with a dark green overtone and the other one had a fantastic dark green-blue color with golden-violet overtones. Both had excellent natural luster and were flawless…where are they today I wonder???

Harvests 2001-2003

Those were chaotic years for me and I did not have any precise records of the harvests. There is a whole story behind this but just so you understand a bit: in 2001 I left this beautiful pearl farming venture behind, said goodbye to all my friends and I started a new career in the touristic industry and then in education. Because of this I did not participate in the production nor harvests nor in certain catastrophic events such as hurricane “Marty” in 2003.

So, from the photographic records of Enrique and Manuel I was able of “rescuing” some amazingly beautiful specimens such as this oval shaped 8 mm “Gem+ NS” grade Cortez Pearl (“NS” stands for “National Selection” or you can simply translate it into another “+”, and this sub-grade is given to the most colorful –or “erotochromic” pearls), this pearl was harvested in 2003 and was taken with the help of a professional camera (you can see the size of the lens on the pearl’s reflection).

The photo below shows some of the most “erotochromic” pearls of 2002:mejores del 2002

Up until this moment we did not name our best pearls systematically…and there is no obligation to do so yet. It is something that has to “feel right”.

Harvest 2004

This year was very interesting for us all: I returned to my post and became a “Founding Partner” (for the first time ever the farm was ours) and we had the help of our friend Alberto Tirado who helped shoot some professional looking  photos than those we obtained from our trusty Sony “Mavica” digital camera (it had a 3 1/4” floppy!) that took these amazing 640 x 480 pixel photos (half a Meg!) but its lenses were really good for zooming.

Here I have the best 4 pearls of the Year 2004…

Harvest 2005

Back then I still did not own a good enough digital camera. I had purchased an HP 2 Megapixel digital camera that took good enough outdoor photos but not on close-ups of pearls. Some of the best –and largest- pearls of this particular year appear on this photo. This year we start seeing pearls in sizes larger than 10 mm and up to 14 mm.

Harvest 2006

I finally have a nicer camera. I still own a Cannon digital camera with 8 megapixels with a good enough zoom lens. Here I present you with the most beautiful and colorful photos of the harvest…and many are clearly “erotochromic”.

Pearls Harvest 2006 colorful BAR

What is “Erotochromia”??? Well, I basically came up with this word about a week ago when I was looking at this year’s beautiful “bi-colored” pearl. I have defined it as a “Very pleasant and Intense color with a sensuous expression”. You may say this is just non-sense (you have a right to do so) but to me this is very real: these are pearls with such beauty  that just make my eyes turn white. Photos are simply not enough to show you’re their beauty…which –after all- is totally Dynamic.

For a short moment I believe I should have called them “Chromorgasmic” but thought otherwise.

Harvest 2007

Our harvests have slowly improved with every year: with more experience comes better judgment and even some technological improvements; under the threat of climate change we have tried to adapt to a changing environment by using different aquaculture techniques and methods. Overall, the size of our pearls has increased to an average size of 9 mm(up from 8 mm), and our pearl shapes have become softer too (initially our usual shape was of BAROQUE  shapes -80%-and now we are down to 60% and our Baroques look symmetric) and the luster and skin beauty have also improved.

2007 Harvest Color Flow (4)

On the photo above we arranged the pearls in a way that you can appreciate the range of colors we obtained in 2007’s Cortez Pearl Harvest, but you can easily id the most colorful ones.

Closing Remarks: This has been a very quick recap of some of the best Cortez Pearls of for 12 years. These Special Pearls are the ones that helped us trace a route to where we want to arrive…the “goal-setters”. What was our initial passion??? It is still the same as it was years ago: To produce the most beautiful naturally colored cultured pearls in the World, pearls that will cut your breath short…

In my next post you will see more pearls that have their own names and that defined that year in pearls. I hope you have enjoyed this small stroll through our harvests, so until next time Smile

Our Newest Cortez Pearl Jewelry 2015

This has been a very good year for our Cortez Pearl Jewelry store. Not only do we still have the majority of our excellent jewelry designers but we now have even more talented people working on jewelry pieces that I am are sure will light you up!

So, I want to take a bit of time to present you to these new designers. Many of these items are already available at our e-Store, so I also invite you to view additional photos and information –including price- right there. Please don’t say that I did not give you enough time to see these pieces: just yesterday we sold 2 of these!They sell fast.

Cortez Premium Jewelry Line

This new design line is lovingly designed and hand-crafted, with special intent on detailing. Crafted in solid 14K Palladium-Gold in a perfect mix that will ensure that your jewelry will keep its beautiful white color forever (unlike items that just have a coating). This Premium line also incorporates diamonds –on some items- and most importantly: GEM GRADE Cortez Pearls.

This is an entirely CLASSIC line of jewelry, with long-lasting VALUE since its style is not reminiscent of a time or epoch and will outlast any fashion style constraint. If you are looking to handing down an heirloom piece of jewelry in your family, the Premium line will be something that you will find at our e-Store and jewelry store in Guaymas.

Fabra Designs

We are happy to announce that we have a new designer from the State of Zacatecas, a state that has been known for its silversmiths. The items are very modern and just PERFECT for the taste of modern men and women.

The jewelry is made using pure 0.925 Silver and leather (in some instances), they are solid and substantial, with an elegant, modern and minimalist design.

Elegant Filigree by Eva Souto

Eva Souto has provided us with the most beautiful and dainty filigree pieces we have ever seen. Her 0.925 Sterling Silver jewelry designs have a touch that combines modernity and tradition, which in a way is something very Mexican: it keeps up with the best of our heritage but that it also takes leaps towards modernity.

It is an absolute PLEASURE to examine the delicate and elaborate hand-work of Eva’s silversmiths, and then combined with our colorful Cortez keshi and cultured pearls…they just unravel into a very exclusive line of jewelry that you will not be able to find just everywhere else.

My next blog entry will have more information about the new designs from Carlos Cabral, Alejandra, Tania María and Kathe Mai, so stay tuned!

Have a great week!

7th Annual Pearl Ruckus Report

Yes! I can hardly believe it has been 7 incredible years of Pearl Ruckuses, and each year they get better and better. But, what is a “Pearl Ruckus”??? Basically put it is a special gathering of friends, pearl collectors, pearl buyers & resellers, designers and pearl farmers…but in the end it is really a gathering of pearl lovers in a fantastic Mansion-like setting.

Pearl Mansion

You may remember some of my previous Pearl Ruckus series of blog entries before, but in case you haven’t I do have to emphasize that this very special gathering is the result of the work done at the website, basically the World’s Largest Pearl Information Source, and this site is a labor of love of many people that LOVE pearls, including: Jeremy and Hisano Shepherd of fame, Caitlin Williams (Caitlin) and Blaire Beavers (GemGeek) (as the site’s admins) and of Newberry, Pattye, Mikkey and many more brave pearlers that share and spread the Pearly Gospel Winking smile

So, here are my 3 HIGHLIGHTS for this Year’s Ruckus and #1 is actually very, very easy:

#1. Little h Video

Jeremy and the team at created a short video of Hisano sharing her inspiration and design process for her little h, Pearl Geode and Finestrino collections. It is a delightful video and the jewelry pieces are some of my favorites!

#2. Kojima Pearl’s Amazing Cortez Mabe Pearl Necklace

Stunning. I obviously prefer my pearls above all others (but if you follow this blog you know I am also a fan of Kamoka and Kasumigaura pearls)…last year we came up with a pair of beautiful Mabe Pearl necklaces set in Sterling Silver that were all the rage (one of them is owned by U.S. Senator Gabrielle Giffords) but this year I did not have anything similar to offer…but what a pleasant surprise when Sarah and Mounir came up with this AMAZING Cortez mabe pearl necklace…simply stunning!


Sarah and Mounir have become an amazing designing team…just ready to rock the pearl world! For more information you can head to Kojima Pearl’s website.

#3. The Pearl People

The Pearl Ruckus is ultimately about PEARLS…but without PEOPLE to admire, love and wear pearls we have nothing! So in the end it is all about People that Love Pearls.

And at the Mansion we spend almost an entire weekend immersed in pearls, pearl jewelry, incredible food, music and making friends. If you ever feel like you could become a “Pearl Ruckrusader” (just made up this word) please join us at the forum and start meeting the people! Maybe next year you can join us too! Open-mouthed smile


And besides the friends, the talks, the music and the food –and everything surrounded by pearls of course- there were many other interesting things including the “Pearl Talks”:

Josh y CelesteJosh Humbert of Kamoka Pearls gave us a great slideshow presentation. Josh is not only an extraordinaire pearl farmer but also a most accomplished NatGeo photographer. Wish I could share the photos here…but they are his to share so if you want to see some of his work just contact him via Tweeter at @KamokaJosh.

Here we have Josh and his life-mate Celeste Brash. Good friends of mine.

BlaireBlaire Beavers gave a great talk and walk through memory lane…first by reminding all how the name for this event was coined…yes, my good friend Michael Rivers came up with this inventive name and it sure has stuck. All 6 previous events were considered…so many years, so many great moments! We had to laugh and smile at the photos of the pearl tiara wearing comrades and the retelling of the “Purloined Pearls” story, or draw our breath inwards at the wholesome beauty of many beautiful pearl necklaces and jewelry pieces.

SelfieDouglas McLaurin (that’s me!) also gave a short talk on Cortez Pearls…this year I tried a less serious approach and resorted to much more humor than before. I don’t know if the audience agreed with me but I hope they had as much fun listening to my “La Peregrina” pearl section as much as  I had making it.

I also took a bit of time to talk about this year’s Cortez Pearl Harvest: it was not as good as last year’s (every year results in a different harvest due to environmental conditions, as you would also expect for wine, cheeses, grains, etc.) but it was a very good one nonetheless. We harvested almost 4 kilos of Cortez Pearls (roughly 4,000 pearls) in sizes between 8 and 13 mm, the average size for this year being 9 mm. The pearls were also rounder than any other previous harvest and very lustrous, with a better “skin” (less flaws and imperfections) but the colors –for my personal taste- were less intense.

Cosecha 2015

If I had a way to describe the overall look of this year’s harvest it would be: Silvery Gray with Blue Overtones. There were –of course- the traditional stunners…but I missed finding Red and Blue pearls, there were more coppery-golden ones this year too.

Jewelry Highlights

Oh yes! My good friends had Pearl Jewelry on everyday and would change their jewelry based on clothing, mood or even environmental conditions Smile Such a fun crowd to be with. Here are some of the highlights:

A very beautiful Cortez Mabe Pearl pendant in Gold with Rubies (owner: Rhonda).

Cortez Mabe Pendant Rhonda

Another beautiful & stylish piece in gold with Cortez Cultured pearl and many Cortez Keshi pearls, designed by Sarah & Mounir at Kojima Pearl. (Owner: Catherine).

Keshi Cortez Sarah Design

Another favorite of mine are Hisano’s amazing Geode Pearl jewelry…just stunning, and the colors are just to vibrant!

Pearl Geodes 2

And there are many, many more stunning pieces but I just did not have the time nor adequate light to shoot all those pics I should have had!  But I will close up this entry with just one more photo and description…

My friend Sheri Jurnecka has come up with a dazzling array of uniquely shaped squiggly octo-jewerly designs and she has used all types of pearls on them: blacks, golden, freshwater and Cortez Pearls of course. Hope you enjoy this beautiful cephalopod family photo!

Until next time…Cheers!!!

The Weirdest & Funniest Pearl Farm in the World

And this is basically the way we were designated by National Geographic in their “World’s Weirdest” TV Series, under the “Funniest Farms” banner. The program aired back in February 14th of 2014 in NatGeo’s TV network but we were totally oblivious since the program has not been dubbed nor sub-titled and has never aired in Spanish speaking countries. So we just kind of forgot that we had been visited by Nick Patterson and Pete Allibone of WAG.TV productions back in December of 2012 to film our pearl farming operation (you can go back an read all about it here), but then about a month ago we heard from some of our visitors that they had seen the episode where our farm was featured!

NatGeo's World's Funniest

I started looking for the program and almost immediately hit a wall: not available in YouTube and when I found it in both Amazon’s video service and on Xbox Video I was really happy! until I noticed it would not allow me to buy it because it is not available in “My Region” (whatever this means while on the Internet). This was a total let down…so I got in contact with good old Nick (who was placidly tanning himself somewhere in the Caribbean) and he sent me a link to watch the whole show. Finally, after only 18 months, we could finally see the end product of that long and interesting work day with these absolute TV professionals. The results were amazing.

Since I cannot share the entire video for obvious reasons, I decided to make a very short (40 seconds) video of the episode on the pearl farm. It obviously lacks everything but gives you an idea of what to expect, so I do hope you will enjoy watching it.

Personal Thoughts

I really enjoyed the show. Found it has a disturbingly interesting way to entertain, amuse and befuddle you with words like “feces”, “testicles” or witty comments such as “…if the oyster dies, I can always eat it!” when I was operating an oyster. But above these…the imagery: Pete had a great chance to film that day when they visited us. A cold-front was coming in and we had a major fog-bank in the bay, which led to one of the best and most beautiful time-lapses I have seen of this area. Simply stunning.

The end result was entirely eclectic: a mixture of seriousness and humor, of marvelous photography of Bacochibampo Bay amidst the fog and of the pearl seeding operation, of the pearl farm and of the pearl harvest. Basically: the whole enchilada.

It was truly a very professional job and we are very grateful to Nick, Pete, the crew at WAG.TV and NatGeo for their visit and for showing the world our curiously weird and little pearl farm in the Sea of Cortez.

Do you want to know our Pearl Farm??? What are you waiting for!!! Guaymas and San Carlos are a marvelous place to vacation and you can also visit one of the World’s Funniest and Weirdest Pearl Farms in the World…right here in Sonora, Mexico.

Unusual Vampire Mabe Blisters


Whoa! This year we have a very special group of out-of-the-ordinary Cortez Blister Pearls…why are these so Special??? Well, let me explain:

  1. Many of these are BIG! As you are well aware our “Rainbow Lip Pearl Oyster” (Pteria sterna) is NOT a Big oyster, more of a mid-sized animal…just between the large “black/silver/gold lips” (Pinctada margaritifera & Pinctada maxima) and the smaller “Akoya Pearl Oyster” (Pinctada imbricata=fucata). The average size of our Cortez Mabe Pearls is 14 mm in diameter.
  2. These Cortez Mabe are VERY BAROQUE, or beyond baroque or simply put: Naturally Shaped. Our Mabe Pearls are never identical and are mostly free-form but leaning towards oval and teardrop shapes.
  3. Their RARITY: this group is very unusual and rare…just 21 pearls out of a harvest of over 2 thousand that we harvested in 2014. Yes, basically just 1.05% of last year’s harvest!
  4. Their ORIGIN: now, this is the final nail in the coffer in a manner of speaking! Why, because this group is basically made up of 100% Natural Blister Pearls that have –for the first time- been processed into Mabe.

Are these really Natural????

Yes. And there is a special story to these. Let me tell you this story.

Back in 2012, when we were seeding our pearl oysters we started to notice something odd in them…snails. There were hundreds of these snails we had never seen before. There were so many that we found them with the oysters and we started noticing some INSIDE of the Rainbow Lips too!

Caracol Adulto que creemos esta metiendose en Pteria sterna (1)

At that same time we received a group of Malacologists from Florida and we told them about this issue, they kept some specimens and headed back. Manuel and I started looking for the name of this unknown snail and we came up with the same name, later we received confirmation from Florida: Vitularia salebrosa, an ecto-parasitic snail of the Murex family. This blew my mind!

I had never seen such a variety of snail before and I had never seen how they actually found their way inside the oyster’s shell to suck its blood like an armored leech (yes, they suck the blood of its host), you can actually read all about it in this scientifically detailed article.

Well, the oysters don’t have their “Vampire Hunters” but instead they use the millennia old trick they know all too well: if it harms you, turn it into something beautiful…just make a Pearl!

But at the moment I was looking at these snails I just wanted to know more about them, and because of this I just left the snails inside the oysters allowing Nature to follow its course. And Nature did its thing.

We collected and photographed some of these nails, we found them in all colors and sizes. That year was the year of the Vampire Snail.

Caracol, snail, Vitularia salebrosa 044

We find them rarely these days. Must have been one of those “weird natural cycles” that Nature usually surprises us with. Unfortunately I can’t seem to find the photos I took of these snails as they were being coated with protein by the oyster. I kept one shell with its snail, but dehydration has pretty much damaged the shell.

Vitularia salebrosa in Pteria sterna shell (1)

Vitularia salebrosa in Pteria sterna shell (2)

This is the first time ever such an event has been described with these species of mollusks.

Another very interesting and noticeable feature is what I would call “Health”. Sick or unhappy oysters usually have a very dull shell, whereas “happy” or healthy oysters display beautiful colors. The oyster shell with the parasitic snail looks quite unhappy.

Shell comparisson

So, now you finally understand why these pearls are all so Special and Unique. In a way they tell us a unique story of how we can all withstand pain, endure and ultimately create something beautiful from it.

If oysters can do it, so can we do it. It is your choice to create your own glorious pearl.


On Sale Soon!

These pearls will soon become available for purchase in our e-Sales website, but you can also write to secure your own! Remember we only have 21 of these ready for you to set them in Jewelry and enjoy Nature’s perplexing beauty.

P.S.: I hope you don’t write in to tell me that “Pearls are produced by a Grain of Sand”. I finally have overcome my anxiety towards this myth and won’t go into a fit 😉


Our Pearl Farm is becoming more Known

OK. Tried my best to do a play-of-words with the title (have I failed miserably???) and the contents of this entry. This is all about the recent visit of the crew of Mexican Magazine “México Desconocido” (it would translate into “Unknown Mexico”) to our pearl farm just last week! (May 22nd).

If you follow our Blog you may have heard that we appeared in this magazine in a full-fledged article back in the year 2007. The article was called “Sowing Pearls and Dreams in Guaymas” (lovely title, unfortunately not translated into English but you may use a translator to achieve a minimum degree of information). The article was really well written and had some really good photos. We are very thankful to Mexico Desconocido for this chance to appear before their audience.

The photos I mention do not appear in the on-line version of the article so I prepared this small collage of the article that will give you a better insight.


This year, Mexico Desconocido has returned to Guaymas and decided to re-visit us. On this occasion we are not going to be featured in a unique article but instead we will become a part of an article about Guaymas-San Carlos, showcasing our local beauties and attractions…the pearl farm is –of course- a major attraction in the area.

So our own Manuel Nava took the reigns and received our friend Mariel Rivera –she is the head of the local visitor’s center in San Carlos- and two young reporters from this magazine so they could visit our Pearl Farm in style…they even had a boat ride to the farm.

Finally, they had the chance of seeing the end product: thousands of colorful cultured and Mabe pearls! Mariel even tried on some of our amazing new jewelry designs made 100% in Mexico (pearl, silver, design and workmanship).

So, now that you have seen that “Unknown Mexico” knows about us…What are you waiting to come and visit and know more about the farm and its pearls???

I mean…specially if you are in the vicinity, the next closest commercial Pearl Farm (by this I mean a REAL pearl farm and not a tourist trap) is located in Fiji, some 10,000 kilometers (6,000 miles) away from us!!!

Guaymas is much closer (unless you are not of course and you are reading this blog in Fiji itself) and we do have these great places to eat, beautiful beaches and sunsets, stunning desert views and diving and fishing enough to satiate your desires…and did I mention… PEARLS????? Yes, we have them too.

So, just come on over and enjoy our hospitality! Hope to see you down here at the farm soon.

The 2015 Tucson Gem Show part 2 – Final comments

Amazing. We are are almost about to start with the month of May and I am about to write about things that happened way back in February. Goes to show how tight a schedule I have.

But here I am again sharing my thought and comments, hoping some of these things will be of help and interest to you all. So, let me know start with the JEWELRY, a most pleasant subject.

This year we were pleasantly surprised by our many talented friends. Kathe of TriGem Designs, Alejandra of Alejandra and Sarah of Kojima Pearl have been busy producing some of the most beautiful Cortez Pearl jewelry designs we have been able to see these last years. Gold, silver, gemstones and Cortez Pearls are all combined to produce wearable beauty to please the beautiful women that grace our fair Earth. Let me show you some of the beautiful pieces we saw in Tucson this 2015 and some that even made it all the way to our Cortez Pearl Jewelry store in Guaymas (and that you may also see in our eStore).

Kathe Mai of  TriGem Designs

Kathe’s jewelry designs may be easily explained with just one word: Timeless. These are classic pieces that could have been worn 100 years ago, but also worn today and will be worn 100 years from now. Simply put: these are jewelry designs that will not suffer from the ravages of “fashion statements”. You may agree or disagree with me…but I believe you will agree these are beautiful pieces, and all of their accompanying stones are Fair Trade Gems as usual.

Another great thing about her jewelry is that it feels equally at home being worn with a fancy night dress or with just normal day wear such as jeans. My personal favorites are the 14K Rosé Gold with Cortez Mabe and Nyala Rubi piece and the 18K Yellow gold Cortez Mabe piece that has little moveable gold waves…reminds me of a jellyfish.


This year Kathe came out with more Cortez Mabe Pearl jewelry designs and she is also busy preparing a new line of jewelry for this year…a special line that we will not disclose until it is ready. Expect something special later this year!


Alejandra Solomone of Alejandra Jewels

Alejandra has a hectic and contrasting life: she moves and feels equally at home in the great city of New York and her mother’s ranch in the Sierra Madre in Mexico. Quite a contrast! She is both a sophisticate cosmopolitan woman and a horse mounted Amazon and her jewelry also defies our imagination with its colorful designs.

This year she incorporated even more colors in her new designs –all of them available at our eStore and here in Guaymas- with the help of beautiful Mexican Fire Opals, Granates, Sapphires and Diamonds. This year she worked wonders on our Cortez Pearls, Mabe and Keshi.


Yesterday we were preparing our first ever TV commercial (to air on State television here in Sonora and in TV Azteca Arizona) and Rocío chose a pair of beautiful earrings by Alejandra for this special occasion. I believe you can agree they look stunning.


Sarah Cannizaro of Kojima Pearl Co

Our dear friend Sarah is increasing her Cortez Pearl inventories and she has been coming up with many special requests by pearl connoisseurs…her recent designs also incorporate the inspiration of her husband Mounir. You can see his vision on the pair of Mabe Pearl earrings, a great contrast with the violet stones and the Cortez mabe pearls.

I expect to see many more great designs from Sarah and Mounir in the years to come. You can find more of Sarah and Mounir’s jewelry at the Kojima website…and they also carry a great selection of Kamoka Pearls -from our friends Josh and Celeste- and have exclusive Kasumiga pearls as well, so you can’t really go wrong with Kojima if you intend to find that “special pearl” that we all are looking for.


And that is that in the case of Cortez Pearl Jewelry at this year’s edition of the Tucson Gem Show. For now I will shift gears into two very different subjects: Great Food & Great friends and Mexican Fire Opals.


Mexican Fire Opals by Opalos & Artesanias Mexicanas

I love pearls above all gemstones. In a close second place I have Opals, followed by Emeralds and Amber. I am not that fond of the shiny, glittering stones…but Fire Opals are special to me, they can also have such varied looks! I mean: some can look glacial white, others are a flaming orange, then bright Yellows and even a soft soapy pink! You would think you are talking about different stones but no, these are the Opals of Mexico and our friend Luciano Tamayo and his family are the owners of the best mine in Jalisco. They have taken the art of Opal processing to a new level and offer them in very conceivable shape, size and colors…from minimalistic rough-cut opals to perfect cut opals and everything in between like the baroque shaped opals that Alejandra used in her Cortez Keshi and Opal earrings.


Our friend Luciano and his family are always ready to take care of your special Opal needs at the Tucson Gem Show (same tent as we are, the GJX just across from the Tucson Convention Center) and you can contact them via e-mail too.


Great Dinners with Great Friends

I believe the Pearl Industry is special and different from all others. Over the years you end up making great friends, all sharing this common passion for pearls and jewelry. This year we had our nights filled with laughs, merry drinks and great food…but it is the friends we join the ones that actually make it a special moment. Thank you all for your friendship, for being gracious hosts and for sharing your love and knowledge of pearls (and Spirits!) with us.


And with these last words I bid you all a Great Spring!

The Tucson Gem Show, part 1

February 4th, 2015: Here I am reporting from Tucson, Arizona, in what is considered the largest international gems & mineral show, a city that becomes a haven for precious gems, semi-precious stones, fossils and all kinds of jewelry in the world. This year -and every year since 1995- we are displaying our exclusive and unique Cortez Pearls, and every year I try make a small report about the people, companies, products or events that drew my attention,and this year is no exception.

But before I begin with a general report of 2015’s Tucson Gem Show I want to start with a very quick report about our Cortez Pearls production. I will begin with the information about our 2014 Pearl harvest.

The 2014 Cortez Pearl Harvest

The year 2014 will go down in the annals of our history as a bittersweet year: we had the best pearl harvest in our history: after more than 15 years of commercial pearl production, we finally reached the goal of the 4 kilos of Cortez Pearls (this means just around 4,000 pearls). But despite the very good news, we also had problems with the environment (global warming) and this resulted in a very high mortality in the group of oysters that will allow us to produce pearls in the year 2016. Because of this reason, we have had this bittersweet situation.

Some of the novelties of 2014 and that we are showing here at the Tucson Gem Show are these:

We have a new variety of Cortez Mabe Pearl on sale: we call it the “Mini-Mabe”, these are Mabe pearls that have a lower dome height and a smaller diameter (this means, much smaller than traditional Cortez Mabe), but this gives them a lower value of investment and -in addition- it also allows the jeweler or designer to use less metal to produce jewelry items that are more affordable for the end user. These pearls have been used by our Australian distributor (Raw Pearls of Adelaide) with great success, and these lovely little Mabe have caused a great impact at the Gem Show and are all but almost exhausted.

“Raw Pearls” – Turtle Pendant w/CortezMini Mabe


For this show’s gems have been exhibiting the Cortez Pearls of the 2014 harvest (the 2015 harvest will take place in the middle of this year) and among the most important items I have to mention is the beautifully unique 2014 Cortez Pearl necklace. This beautiful necklace consists of 43 cultured pearls from the Gulf of California, all the pearls were produced by our exclusive “Rainbow Lip Pearl Oyster” (Pteria sterna) and was made with pearls of at least 6 different yearly harvests. This multicolor, graduated necklace is made with pearls that measure between 8.3 mm and 10.6 mm, with the central Pearl -an incredible dark purple-red Cortez Pearl- measuring 11.3 mm. What else can I tell you about this beautiful necklace? It is an extremely rare piece, this would be the 11th Special Cortez Pearl Necklace that we have produced with this finesse and quality… and it’s a uniquely special piece, the owner will even have the right to Christen it with a unique name and this name will be linked to the necklace for generations to come.

Cortez Pearl Necklace 2014

Among the pearls that came to Tucson, we have the large Cortez Blister Mabe Pearls, which this past year were more abundant than in other years, but that ultimately are a little more than 100 pearls… these pearls have beautiful colors and larger sizes (reaching up to 5 cm/2” in diameter), and are perfect for producing pieces of jewelry with a high visual impact.

Cortez Mabe Blister

In general this year’s gem show had a special flavor to it, something which I had not felt in many recent years and that I can only describe in a single word: enthusiasm.

This enthusiastic atmosphere seemed widespread amongst buyers and most of the sellers, and I believe this optimism may be due to the recovery or improvement of the United States economy (although customers from Canada and other oil exporting countries were not in the same spirit). Let us hope that this spirit will also translate into an overall growth of the international jewelry industry.

Note: The information you have read up to the previous paragraph was written while at the Tucson Gem & Mineral Show, but as of this moment the report was written on February 11th. There was simply too much work at our booth and I could not continue with a “live and direct” report.

Elisabeth Strack’s Pearl Presentation (AGTA)

The AGTA carries out seminars and lectures by expert gemologists, designers and industry analysts every year. This year was no exception and we were lucky to go to the presentation of one of the foremost authorities in the world of pearls: German Gemologist Dr. Elisabeth Strack, author of what many (myself included) consider to be the Pearl Bible: “Perlen“.

The presentation took place on February 4th at the Tucson Convention Centre and  Dr. Strack spoke mainly about three issues:

1) the “new wave” of natural pearls, mainly made up of non-conventional species (non-nacreous pearls from snails, clams and even the Nautilus) and

2) a review of some pearl innovations, such as the RFID enabled Pearls and the “Provoked Baroques” as well as a redefinition of freshwater pearls based on their production system (Note: if interested, my friend Caitlin Williams wrote an amazing article on the Evolution of the Freshwater Pearl on the website. I recommend Caitlin’s article wholeheartedly).

3) the Natural Pearl Market: Something that seems very important to stress is that Dr. Strack explained that the way in which you can assign a monetary value to a natural  pearl no longer obeys the “old pricing rules” which seemed to function for centuries; she basically states that today the value of a pearl is just a “thing of the market”, where the price of the pearl basically depends on what a customer is willing to pay for it. Wow.

She mentioned the famous that the once popular pearl pricing “Rule of Tavernier”, named in honor of Jean Baptiste Tavernier (a great Explorer and French merchant of the 17th century who discovered the famous “Tavernier Blue” diamond) is no longer the “rule of thumb” for natural pearl pricing. This rule basically consists of a system based upon two factors and their interaction:

  • The “Size Factor“: basically the weight of a Pearl is obtained in grains (a grain being equal to 64.79891 milligrams) and this value is then multiplied by itself. Thus, if a Pearl weighs 4 grains its size factor value will be equal to (4 x 4 =) 16.
  • The “Multiplier Factor” or of Quality/Beauty: Tavernier established a range between 0.5 and 30 as a possible value for the pearl’s quality or beauty.  Pearls of little or no beauty will be valued between 0.5 and 3, while the more “normal” pearls fall within the range of 15 to 20, and exceptionally beautiful pearls -the so called “gems”- will fall within the range between 25 to 30. Once you select the appropriate number you proceed to…
  • Multiply the Factors: take the resulting number of “Size Factor” (SF) and that of the “Multiplier Factor” (MF) and multiply them. In an example, lets us say that we have two pearls, one being very beautiful (MF = 30) and a far less graceful one (MF = 0.5); if both weigh the same (8 grains, SF = 16) then we have that the price of the gem pearl will be $480 and the less graceful one will be worth just a mere $8.

And in what currency is the value of the Pearls set in the examples above? In US dollars according to Strack (for more information, you can consult Elisabeth Strack’s book “Pearls” on pages 297 and 298). I assume that there was another currency in use in the times of Monsieur Tavernier, very probably the most international currency of the day was the “Mexican Peso” (also known as “Real Español”), but Dr. Strack found a way to upgrade its outdated value to a 2006 equivalent (date of the publication of her book). We are fortunate to have it so easy.

But again, for Elisabeth Strack, the price of natural pearls today is completely out of all rules and simply depends on the “market”.

An example she provided with a pair of natural Pteria sterna pearls, the same oyster that we use to produce our beautiful Cortez Pearls, is revealing. In this example, she had the photo of two tear-drop shaped pearls, one of weighing 10.15 ct (carats) and the other one at 1345 ct; these were sold to a final price of $2,600 to $26,390 USD USD/ct…equivalent to some by smaller Pearl and $34,970 USD by the greater size.

Having used the rule of Tevernier, the value of these same pearls would be a little different (I’ll use a 15 FM as an example):

  • 10.15 ct = mg = 31.33 2,030 grains then 31.33 x 31.33 x 15 = $14,723 USD
  • 1345 ct = mg = 41.51 2.690 grains then 41.51 x 41.51 x 15 = $25,846 USD

In this case the price could be very different, since I don’t have the actual MF value assigned to these pearls, but changing this value would obviously make a huge difference.

It’s really rare to find pearls like those in the example above, so if you do find a natural pearl… first you should consider its size/weight and then its beauty. Please do not become too emotional with the price and then do consult with an expert in this field before you actually tell your boss you quit and will move next to your favorite movie star’s house.

It is very important that you know and understand this: these prices are the end customers pay. What I mean by this? That these would be the prices that people pay as Bill Gates, Carlos Slim, Paul Allen, Mark Zuckberg, etc… and not are prices that could pay the intermediaries, which are those who buy these pearls and can offer them to another intermediary (the famous Jewelers like Tiffany, Cartier, Harry Winston, etc.) who is who ends up offering these gems to moguls. The only way in which you could access these prices is you go directly to the final customer… it would be good to know them and they you know you so you open up the doors.

At the moment it is the information that I am going to share this great annual event in Arizona, but next week I will continue with additional information about the event. I hope that the information is of utility and interest and here my kind readers I’ll be sharing my expert advice with you.
