    I got that the naturals Douglas refers to are precisely from his farmed P. Sternas, and the colors agree. His statement that those he cannot absolutely prove to be natural are folded into his keshi lots gives further indication.

    Just the opposite of the keshi/natural crisis currently facing the pearl labs (integrity vs. criminality).

      Great photographs. Thanks for sharing them and your information. Would you just clarify exactly which mollusks produced these please, the Pinctada mazatlanica or the Pteria sterna? The overtones are very Pinctada sterna like. I would also be interested in knowing how you are certain they are natural? Are they found in wild oysters from the ocean, hence have never been near a farm and also obviously never been operated on?

      Thanks again.
      These that I have posted are all from our Harvest of Rainbow-Lips (Pteria sterna). All farm-raised animals, but that have never been operated. You see, when the oysters are 2 years old -ready for operation- we examine them and sometimes find natural pearls...so we just keep these animals aside for 2 more years. Easy.
      We know we should obtain naturals in our oysters because we ARE in a rich pearl yielding area.

      I will post a natural Pinctada mazatlanica pearls in this post...and you will see how more "typical" they are. Rainbow Lips produce amazing pearls.

      So, the pearl below is a very nice drop, great luster...but color wise... bland. It was obtained from a Mexican Black-Lip, here in Guaymas. Measured 10 mm at its widest.

        The way we ascertain their natural origin is because we find them inside their natural pearl sacs. If the sac breaks and the pearl falls from it before we can shoot photos or a video, then...it has become a "keshi". So, it is very important that we are careful when harvesting the Natural Pearls.

        You can see how we obtain the natural pearls on this VIDEO.

          Thank you for the clarification. I did not understand that you were seeing the natural pearls in the pteria sternas before grafting, so I concluded they had to be Mazatlanicas- in spite of their color. Silly me.

              And back with some new photos... another "black pearl" from Pinctada mazatlanica. As you can see from the photo, it is a light gray with a beautiful green sheen and violet. It could pass as a Rainbow-Lipped Pearl (Pteria sterna), but we saw it coming from a black-lip and -of course- it does not display the typical pink-red UV fluorescence.

              The next one is a natural pearl cut in half...lovely is it not? The inner structure tells you so much about the life of the oyster. This one was an 8.5 mm near round pearl. If you look at the inner part you can see the pearl was not round -more kidney shaped- and the additional coatings started to "round-out" its shape...next you see the pearl and its host oyster...

                  Good luck, I say, to whoever wants to hunt for keshi inside cultured pearls. If these are the false negatives, I'll burn them for you...

                  LOL!

                  Douglas, keep them coming.

                    Lovely indeed.

                    Identifying and seggregating naturals in pre-graft specimens is an art itself, and an important step. There have been too many myths about naturals and too many claims about keshis. Thank you for your clarity.

                    Palpitation?, Visual?, Both?

                    Either way, these beauties are worth the extra effort, Douglas.

                    In post-graft specimens, we walk a finer line. You mentioned the importance of pearl sac inspection. Is there is a distinction?

                    In my experiments, I've been able to distinctly identify naturals from cultures in several ways. Size, nuclei, age and location within the tissues are indications.

                      You are right about all of the above! It is an "Arcane Art Form" that can be called upon by those that can withstand the time and effort it takes first with the pre-visual (examining the outside of the MOP), then opening them up for visual examination, thirdly the palpation and if you need an extra pointer: X rays.

                      You CAN identify natural pearls easily... the pearl culture sac is in a distinctive portion of the oyster's inner anatomy (gonad) whereas we only consider the mantle -never the oyster's "bodily anatomy"- as the source of natural pearls. We know that we could get naturals out of the body as well, but for us the "perfect pearls" are found in the mantle.

                      Sometimes they are well worth the time & effort spent...sometimes they are not and this will all depend on the oysters and the environment.

                          Hi Ashley!
                          How are you doing? Did you know that Cortez Pearls has a web store? You can get some without going down there, though a visit down there is super fine. The link, the link, where is it?

                            Hiya Caitlin-

                            Oh yes, I know about the store- and a few other vendors that have done some amazing work with Doug's pearls- but I'd still prefer to visit the actual farm... much more educational, not to mention getting a chance to hold them and drool on those beauties in person! I'm sure you know how I feel, being a bit of a raven yourself lol

                            We've been ok- actually, buried up to our necks in the website redesign for Pure! I can't wait for you to come visit and tell me what you think about the new store, but I'm waiting on the Boss-man to give me the OK to unleash the P-G'ers in there lol

                                Another natural pearl from the Gulf of California. This one is from a Clam we usually call "Almeja Ro?osa" or "Rough Clam" (family Veneridae). Unfortunately I don't have the species' scientific name (I need my long lost book on sub-tidal invertebrates).
                                Anyway, the pearl weighs 2.1 grams and measures 10.3 x 12.5 mm, with an oval-drop shape. Does not display any "flame" structure, but more of the "jelly-bean" attributes of "Conch Pearls". Still it is a large pearl and its host shell displays the site where the clam suffered some traumatic event that led to the birth of this very rare pearl.

                                Hope you like the photos...
