Nautilus Blister Nautilus Blister Hi Everyone, This is a shell recently offered to me showing a nacreous blister from Nautilus. Just another piece to the puzzle.

Hi, The strand graduated from Appx. 4mm to 7mm. The drop was Appx. 11 x 15 mm. I enjoyed making this piece. The Pearls had traveled through many hands and traveled thousands of miles before coming together.

Natural Pearl Natural Pearl Hi Natural Can you please take a Macro picture of the interior of a Nautilus shell exhibiting strong flame structure as seen on your pearl.

Hello, I thought everyone would enjoy this. The strand I purchased From a European Antique dealer. They are Pinctada Radiata (Persian Gulf) The Drop was Purchased From an Estate dealer in the Dominican Republic (Far away from its source, Pinctada Maxima). All pearls were GIA certified. We made...

Natural Pearl Natural Pearl Hi Everyone. I understand the great enthusiasm and I too like a mystery. Until I see something that more closely resembles the interior of the Nautilus shell I will continue to conclude that these pearls are from one of the many varieties of Tridacna. Enclosed is a...

As promised a photo from my collection of clam pearls.

Hi Valeria. The flame pattern is typical of pearls coming from a variety of Tridacna. Most likely tridacna Squamosa. The photos that have been shared on the internet so far have all shown these same characteristics. When I return home in a few days I will post images from a few pearls in my own...

I was recently told that only one pearl has received a Nautilus certificate from either GIA or SSEF. Can anyone confirm that they are in possession of a certificate from either GIA or SSEF stating Nautilus Pearl. This would be very helpful to me as I am trying to establish the legitimacy of this...

This is a good example of pearls from Tridacna squamosa being represented as Nautilus pearls. Like Strack I believe that Nautilus pearls will be of a nacreous composition there by mirroring the interior of the shell.

Hello everyone. I would like to reissue the challenge. Can anyone owning a "Nautilus Pearl" show me a shell exhibiting the flame pattern as seen in the photo provided on this thread. I must disagree with the Calcareous lump comment. Certainly all pearls can not be defined by the properties of an...

Can anyone show me a nautilus shell exhibiting flame pattern. A pearls appearance will undoubtedly mirror the interior of the shell from which it came. I have seen several pearls being marketed on line as Nautilus pearls with (per the owners description) certification from the SSEF or other...
