    Not at all, it's very much alive and more intriguing every day. One of the few 'holy grails' in all of pearldom that all the collective resources of this forum cannot manage to grasp.

    Your excellent photograph does not indicate nacre to me. If you have a more favorable close up (now that we know the size) please post.

    I am envisioning a Nautilus Mite/Pearl of Allah road show and eventual auction extravaganza for the deserving and well-heeled collectors out there.

    Your post is greatly appreciated, Pearlshooter.

    I heard the ask price was 60 000$, but it did not sell.

    No, we're talking about the exact pearl you photographed. I saw Tuesday a picture of two of the nautilus pearls that clearly show the flame pattern. Jeremy saw it too (but says they're clam pearls). I'll ask if I can share that pic on the forum.

    Good close-up shots showing flame-like porcelaneous structure. No nacreous structure there it would appear.

    For those who are not sure of what you mean- what is the Bangkok event?

    The inner structures of that (brilliant, noteworthy) photo are so beautiful. There are images of a spiral at the poles. It seems to echo the shape of the august nautilus, one of the most beautiful of shells, and the paper nautilus.
    (what a cute creature lives in that paper shell!)

    Hi Caitlin - I thought that the link in my post would have been enough to answer your question, but since you ask here is another link that will probably answer it better than I could:

    http://www.git.or.th/conference/home.html

    Is that better? Hope it helps.

    Interesting that the ID of nautilus (especially vs. Tridacna, a bivalve!) pearls should be so debated! I would have thougt quite the contrary, since the list of creatures that produce columnar nacre(like Nautilus, Haliotis and some gastropods with uncertain pearl-making credentials, but unlike any bivalve) is so limited.

    Surely, the columnar versus sheet nacre structures ca be traced in pearls as well as in shells?

    The stuff has been researched to death already, so there should be some rich base for the pearl ID application. If anyone should feel inclined to hang a precise label next to the imprecise price tag of the pearl in question, that is.

    Whatever the pearl came from, the structure looks magnificent! It could be the ultimate carved porcelain

    Thanks for the great images, Pearlshooter. The pearl is a miniature universe of great beauty! But whoever ends up with it will need to display it under permanent magnification. Seems obvious to me that the pearl is calcareous with intricate, symmetrical and harmonious flame, whatever the origin.

    Pardon my stupidity, but what causes the flame pattern?

    As a start, here's a nice overview found on Palagems.com in describing Melo-Melo pearls:

    Flame Structure ? One of the most attractive features of melo pearls is their fiery flame structure. On some pearl surfaces there is a regular pattern of parallel elongated striations that impart a silky sheen. In some specimens distinct microscopic ?flames? can be observed that are actually thin lamellae. The lamellae are almost parallel to one another and when sometimes perpendicular to the axis of the pearl result in a ?pseudo-chatoyancy? effect. Pearls with a distinct flame structure have a ?watered silk? appearance towards the periphery of the sphere. In cases where a mottled texture of white or brown spots occurs, the flame structure is coarse and difficult to resolve to the unaided eye. These pearls tend to exhibit dimpled surface features.
    I'm on a plane headed home and will also be rereading Hubert Bari 'The Pink Pearl' this evening. There is a Gems and Gemology/GIA article accessible to members only that should also be worth reading.

    I can't access the link today. I did access it yesterday. So that program is from the Bangkok event.

    I got out my nautilus shell today and looked at it carefully. the outside of the shell displays a very similar pattern to the photo above. I think someone called it "tiger stripes" which seems more accurate than "flame pattern" in this case.
    There is a band of iridescent nacre and there is some porcelaineous lining inside the shell. Now what would cause a pearl to form in a nautilus shell? That one looks like it was spun into being.
