The microradiographic structures of non bead cultured pearls

[vincent pardieu]

Dear all,
We just uploaded on GIAthai.net and gia.edu websites a new study about one of the main challenges in pearl identification nowadays: The separation between natural and non bead cultured pearls.
You will find this pdf at the following links:

The microradiographic structures of non bead cultured pearls
and
The microradiographic structures of non bead cultured pearls

Hoping that you will find this interesting.
All the best,

Thanks for sharing this great information, Vincent! The updated Pearl Lab course microradiographs were an enormous help in understanding the subtle differences in the internal structure. Having Akira Hyatt as an instructor was a big plus, as well.

Your monograph added some really interesting info to this site! Thank you!

Where can you get NBC South Sea pearls? Who is raising them where, and where do they go to market?

Thank you for your leads Vincent... I have downloaded the files and crunching away at the info. I am writing a small article on Natural Cortez Pearls for our blog (and have much information to share on the subject) and one of the articles in GIA's site is about a "Large Natural Blister Pearl"... well, that shell is a Rainbow Lipped Oyster (Pteria sterna) so this article will be useful as well... Thank you again

Thanks to Vincent for the timely link.

Epecially liked this in the conclusion:

?only the mollusk itself can be certain?

Now there's an honest scientist!
