[snufflepig]

That's so neat, are you going to do something special with it?

What an interesting shape, and isn't that large for pinna? Thank you for the amazing photo.

[GemGeek]

That IS large. It almost looks like a fire agate.

Interesting finding, I would like to know more about this specimen

One more natural pearl of Pinna

[pattye]

Ahh, this one looks like a flower petal~

Given the size and more nacreous looking area on one side perhaps it originated from an Atrina vexillum or at least Atrina species rather than Pinna? Would be interesting to see the shell that produced it. Doubt that is possible though.

Not sure if that info fits that thread, but while you are at Pinna pearls ! I have just read in the march 2015 issue of our Revue Fran?aise de Gemmologie that the first cultured pearl of Atrina Vexillum has just been identified and studied.
The pearl is 10.6 x 9.6 mm (slightly button shaped), weight is 6.92 carats. The pearl has undergone in our national french lab X rays and tomography, revealing a bead inside.
I don't quite see the interest of such a culture in Atrina, but !...

Hi
This pearl was found in this type of shell

Look at that picture! Poor Pinnas. There are less and less of them in the Med. Do you know where this was shot?
