We want to share with you the experience of having achieved the production of two unique -exceptional- pearl necklaces made from pearls produced at our farm in Bay Bacochibampo, Guaymas, Sonora, Mexico.

Both necklaces –one made of loose cultured pearls and the other from keshi pearls- are made using pearls produced by the native Pearl Oyster known locally as “Concha Nácar”, also known as the “Rainbow-lip Pearl Oyster” or by its scientific name Pteria sterna. If you have checked any world pearl production data, you will find that this is the only commercial farm in the world that employs a pearl oyster of the genus Pteria. So, all other pearl farms of the world use the so-called “mother-of-pearl oysters”, which belong to genus Pinctada. Thus, simply because of their rarity, a necklace made of pearls from the “Rainbow-lip Pearl Oyster” is really a very special piece, completely out of the ordinary.

Finally, we could talk with technicalities about the beauty of these pearls… that their Orient or overtones are exceptional, that their chroma or color saturation is simply out of the ordinary, that their natural luster is very high, but I think that anything that is said about these two necklaces simply PALES before what we can capture with our eyes… so we offer some beautiful pictures of these items, and you… you will be the one to decide whether they are beautiful and exceptional pieces.

“Bacochibampo” Pearl Necklace

Bacochibampo Pearl Necklace

Previously known as the “Bicentennial” necklace, but once it passed into the hands of its new owners it received it’s new – and very proper- name: Bacochibampo. This is a word which means “Bay of the Seven-headed Snake” and refers to an ancient Yaqui legend (of which we will talk in the future). It is also the name of the beautiful Bay in which we culture these pearls, thus we found its name to be more than appropriate.

This necklace consists of 41 cultured pearls, but if you recall (see this note) the necklace originally had 43 pearls, but the “missing pearls” were used to make a beautiful pair of earrings to go with this incredible piece.

Additionally, it gives great pleasure to say that this necklace found its residence in Mexico, adding to the number of Cortez pearl necklaces in Mexico to 4 (1 more needed to equal the number of necklaces found in other countries).

“Mares Lucis” Necklace

Keshi Pearl Necklace Mares lucis

Whose name evokes the natural phosphorescence which we enjoy in a warm and dark summer night. This is our first great necklace but made with Keshi pearls. It was made at the request of a client in the US and it turned out to be a very pleasant task.

This necklace has 61 Keshi pearls harvested between the years 2007, 2008, 2009 and 2010. It is a graduated necklace, which means that the size of the pearls gradually decreases from the Central Pearl – of greater size – towards the rear. The sizes of the keshis vary between 3.9 and 6.7 (central) mm.

It was truly a privilege to work in the production of these unique pieces of jewelry. These are durable pieces that are meant to become true family heirlooms. For us the making of these necklaces meant:

1. That we took care of at least four different generations of pearl oysters (2005-2008), each one being looked after for a period of 4 years (this means 12 years of care, work and dedication).

2. The operation of thousands of pearl oysters, so that of these thousands only 1% would give us enough Gem quality pearls, in the sizes and shapes required for the production of these jewelry items.

3. A selection process that involves saving the best pearls from each year’s harvest, so we can have the pearls needed to produce one pearl necklace of this quality, every year.

So when they ask us if we cannot simply make another necklace like these we have to say: “We’d Wish!”… And hopefully next year we also have the opportunity and privilege to produce another necklace like these two… never identical, always unique, but of this same Quality.

The only that remains for me to do is to invite you to watch a short video with additional photos of the “Bacochibampo” pearl necklace…

With great pleasure and satisfaction we announce the presentation of three pearl necklaces for the year 2010. As with all previous pearl necklaces that have been produced in Mexico since our pearl farm started operations, these necklaces are made using pearls from several crops or pearl-harvests; for these 3 necklaces, we have used pearls from the 2010, 2009, 2008 and even 2007 crops. You need extreme patience in order to produce a good string of pearls.

What makes these necklaces so special? Well, they consist of pearls produced in Mexico’s Gulf of California, a region known worldwide for its pearls, and these are cultured using a limited-production (4 kilos) scheme, these are the only cultured pearls that are produced under the “Fair Trade Gems” standards, the only cultured pearls that are produced using a “winged pearl oyster”: the “Rainbow-Lip Pearl Oyster“  or Pteria sterna, thus they are the rarest cultured pearls produced in the world and they also display a pink-red fluorescence under long wave UV rays, and are some of the very few cultured pearls that do not receive any “embellishing” treatments (physical nor chemical) … there are many more things to say about how special these pearls are, but this is just to lay the basics.

What we now need to do is present these three strings of pearls from the 2010 edition:

Necklace 2010 – A

This one consists of a graduated necklace with a length of 20″ (50.8 cm), made with 49 baroque pearls with a size (diameter) of between 8.0 and 8.7 mm, using “B” grade “Cortez Pearls” (“B” grade means that there are skin imperfections on the pearl and that its luster is not very high), the central pearl measure 8.7 x 9.1 mm . However, with its light gray color, unique shapes and its iridescent pearls makes it a truly exceptional piece. It has a simple yellow 18 K gold brooch.

Pearl Necklace 2010 – B

This is an excellent pearl necklace when you consider its price:benefit. It is a baroque pearl necklace, but these pearls are soft baroques (not by human action), in short, although these pearls are asymmetrical shaped they posses very soft shapes that are almost spherical in appearance, thus they look “round” from a certain distance. It is quite uncommon for our Gulf of California cultured pearls to have a perfectly round shape (the reasons will be explained in a future post), thus our spherical shapes attain a far greater value than that of the most common shape: the asymmetric or baroque shapes-so this necklace achieves a relative low cost with great looks or “more bang for your bucks”.

This graduated multicolored 19″ (48.26 cm) pearl necklace consists of 51 baroque pearls with a size between 8.0 & 8.6 mm (diameter) and made with “A” and “A+” grade pearls (this means very good natural luster and a clean pearl surface) of exceptional colors. The result is a rainbow-like necklace with red, green, blue gray, black and purple pearls … As with the previous necklace, it features a plain 18K yellow gold brooch.

Special Edition “Bicentennial” 2010 Pearl Necklace

This is a truly a unique Cortez Pearl necklace, a piece of jewelry fit for a Queen and truly something that very few can own. We’ve placed this necklace at the same level of delicacy -for want of a better word- as some of our finest necklaces such as “Stella Maris” (2009) and “Bohéme” (2008). The central pearl is a gorgeous purple pearl (11.6 mm) with incredible green overtones (obtained from the 2010 harvest).

This 19″ (48 cm) graduated multi-colored pearl necklace consists of 49 near-round Sea of Cortez Cultured Pearls with sizes between 8.7 and 11.6 mm (diameter),  and was made using the only “A+” and “Gem” grade pearls, featuring the most intensely colored pearls available, the highest natural luster and the best surface (“skin”) purity possible using only non-treated pearls. This necklace does not include a clasp, since the buyer usually acquires a specially made clasp for such a unique piece.

So far we have named this necklace as “Bicentennial” (Mexico turns 200 years old as an Independent country this year) but this name will be changed by the owner: in the purest pearling tradition these unique necklaces are named or are “christened” in the manner of other famous necklaces or Pearls of old. In today’s world, the vast majority of necklaces produced do not even deserve a nickname… but high quality pearls with a limited production are still worthy of this distinction.

Where are the other Cortez Pearl Necklaces?

Since our Bacochibampo Bay farm started producing loose cultured pearls in the year 2000, we have only managed to produce eight special pearl necklaces -with characteristics similar to those of the “Bicentennial” necklace- and we have always wanted for these to remain in Mexico, but this has not always been possible. So where are these necklaces? Here’s the list:

  • 3 necklaces in Mexico, including the three most perfect and beautiful: “Stella Maris”, “Bohéme” and “Balandra.”
  • 2 in the United States of America (“Maria” and “Isabella”)
  • 1 in Italy
  • 1 in New Zealand

Understandably, the owners remain anonymous. In the case of “Bohéme” it had the distinction of appearing in the book “Pearls” by gemologists Hubert Bari and David Lam, a book where the authors state (on page 86) the following about the “Sea of Cortez Pearl”: “It is perhaps the most beautiful pearl to have been cultured up to now” (Hubert Bari & David Lam. 2010. Pearls. Skira . Italy. 336 pages).

Where will the “Bicentennial” spend its Time? What will be its final name? That will be known soon …so, stay tuned!
