    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...
    Found it: Chione californiensis. This document refers to Bah?a Magdalena habitat.

    It certainly is an impressive find, especially with shell. A fine pearl by any standards.

    Another (no doubt delicious) flavor for the jelly bean jar!

      The "Chocolate Clam" (or "Almeja Chocolata") is Megapitaria squalida. Very different animal...my guess is actually more towards a species of Chione or even Chionopsis gnidia... but since I don't have my book I can't remember certain traits (number of "ribs" & hinge teeth...technicalities). But here is a bigger shell, maybe someone can help with the id.

      Megapitaria would make nice "cocoa" colored pearls...just kidding...the inner shell is pure white. Check out the looks of the animal here. It is one of the tastiest inhabitants of the Sea of Cortez...but we have yet to find a pearl in one.

        Douglas?we 'crossed in the mail.' Chione it is, note my correction that was being made as you posted. The prior document included some reference to 'almeja ro?osa' (seems like habitats are practically identical) thus popped up in my search.

          We sure did Steve! I am now narrowing the species... can't be Chione californica because the largest size reported for this species is of 68x65x38 mm and this shell is twice that size...but there are just so many Chione species here...might just leave it at Chione humoungous

          Here is another photo of the pearl:

                New Pearls!!! Thsi morning I had a Pen Shell Fisherman here, with his treasure cove of natural black-pen-shell pearls from the "Callo Botij?n" or Atrina maura.

                We don't buy pearls but fishermen believe we do so they just bring the pearls in...we would not really promote or support a pearl fishery (not kosher) in the Gulf of California. Anyway, this small stash consisted of some very nacreous, solid, very jet-black pen shell pearls in sizes between 3 to 5 mm (and some very tiny ones, of course) and some calcitic and protein based ones as well... hope you like them!

                  I certainly like them.

                  You are right about the "very jet-black" part.

                  The egg-like pearl has nice swirls of brown over white and great shape.

                  Thanks for taking the time to show us.

                      Those pearls are a treat to behold! I especially like the caramel and white pearl. Definitely very nacreous black pearls. Mmmmm....

                        The shell is a Veneridae, Periglypta multicostata

                        [QUOTE=CortezPearls;70410]The "Chocolate Clam" (or "Almeja Chocolata") is Megapitaria squalida.

                        This shell is Periglypta multicostata, almeja reina or, in English, Many-rigged venus.

                          Welcome to the forum! Shells are as fascinating as the pearls themselves.

                          Red pearls are my favorite also, though natural color red pearls are only in my dreams!

                            It has been some time gone by, I hope Douglas has some new natural treasures to share soon.
                            No, Midge said, I take it back. I wouldnt get a mink coat the first thing. Know what Id do? Id get a string of pearls. Real pearls. Yes, Annabel said, slowly. I think thats a kind of a good idea. And it would make sense, too. Because you can wear pearls with anything.

                                Wow! Traveling back in time to this old thread I started some years ago
                                An excellent friend of mine sent me a couple of photos and video of a SPECTACULAR drop shaped pearl he just purchased from a diver.
                                Not only is this pearl of a GORGEOUS shape (one of those very rare elongated drops), great luster and almost PERFECT in every way!
                                It was obtained from a huge Mexican Black Lip Oyster (Pinctada mazatlanica) and the pearl weighs just 27 carats!!!! This is CRAZY!
