Would you post a picture ?
I was thinking of a Nautilus shell /osmena, but I am sure you are talking about a real pearl, anxious to see it ...
Please do see if you can get some pictures!
In theory, if other shelled creatures like conch and whelk can have pearls, why not Nautilus shell?
Osmina/osmena (I see it spelled both ways) "pearls" are usually shaped out of the middle of the shell material. It has a very special luster you can recognize as being from a nautilus shell.
Wonder how that works - after all the animal a primitive cephalopodes not among the usual bivalve and gastropods pearl-makers. Anatomical similarities don't go that far.

If this pearl is what it is said to be, that's quite a bit of news!
Well, just a thought. Is there a zoologist in the house?
Here is a peeled nautilus shell showing the osmina core
THAT is a cool picture, thanks!
O looked up nautilus pearls just now in Strack (I'm like a kid with a new toy with this fantastic book.) She has a section on osmena pearls, but for nautilus pearls she says (page 111) :
"Pearls from Nautilus pompilius are absolute rarities. Indeed, it cannot be even said with any certainty that they do exist. They are described as having a baroque or pear shape and a white colour without lustre. Some rare, pink samples have also been reported.... "
Did you notice any sort of chatoyancy or flame within the pearl while you were looking at it? The "porcelain" attribute used to describe the surface reminds me very much of the conch pearls- rather glassy, non-lustrous, non-iridescent.

This is exciting. I feel privileged to be able to one day see close-up photos of such a rare product of Nature!
Thank you for this thread!
Fascinating. We've had references to osmena/osmina here, but not to pearls. 'Pearl Nautilus' converts to 'Nautilus Pearl' on Pearl-Guide!
Waiting for the close-ups, Effisk's photo offers enough detail to intrigue, with suggestions of both flame and opalescent qualities. Appears to be a kind of hybrid calcareous/nacreous creation. And I do perceive a hint of color (rose).
I'll send everyone running to the optometrist with this cropping.
No kidding- the blown out pixels are a little tough on the eyes there! I am tending to agree with you about the slight Rose shading- but maybe that is just an effect of the light? Or the camera? Hmmm
Effisk- thank you for your detailed observations... I must admit: I am very intrigued. Am definitely looking forward to a few close up shots

Nautilus pearls do exist

Nautilus pompilius pearls definitely exist, but are perhaps the rarest of all pearls. As a cautionary note, there is a common object known near Australia as le coque de perle, which is carved from the central whirl where the shell is quite white.
Il faut obtenir certification de SSEF a Basel ou GIA. Je voudrais bien voir une photo tres claire.
