These would do a poppy proud!

I can't remember seeing such pearls in any new jewelry work [wrong continent? - even among historic records there are more styles using such pearls in imported...

Hollow pearls by design described by Gary Roskin along with a theory of how they came to be:

The link below goes to a presentation by a historian with the Metropolitan NY. about the circumstances of a portrait and incidentally, of a rather nice collection of pearls shown with the sitter.

Sounds like these guys have got quite some party going!

I never looked into the pearl color thing too seriously, but akoya have been written of to death [about color selection, see page 27 and 36...

The link at Wiley Inter-science is empty [always happens with these - can't save their links... ] so... I need to ask: what do golden akoya have to do with those other two kinds?


PS: just read...

Something reminded me of this debatable object you have been offered: a strand of large round MOP beads, each bead assembled of two precisely polished halves with 'swirls' reminding of the middle of...

On a second thought: that woman must have known pearls enough - wonder if she may have kept hers as a keepsake from the prank [nevermind which way, Douglas!]. Her foolish man bequeathed his to his...

Good luck, I say, to whoever wants to hunt for keshi inside cultured pearls. If these are the false negatives, I'll burn them for you...

LOL!

Speaking of which,

what of P. radiata? Anyone?


[Ref. AMNH counts modern sources]

On that list, there are at least two stories of a species tolerated like weeds and picked at like the...

With a taste for teasing. The report starts by saying that the pearls looked like not so great beaded pearls of the bag, and suspiciously nucleated upon candling. If I were a crook, I'd be back to...

Wasn't there some sense that beadless freshwater pearls can / should / ought to be called 'keshi' too? That should help put the stuff into perspective.




Wish I knew about these for a grammar...

I remember the video. I find two details intriguing:

#1. there are no traces of 'attack' on the out side of the shell but some are found inside? [the spot does not appear clearly in the video]....

Well, how are the freshwater ones done... It isn't much of a mystery.

The task to identify the traces of the human intervention in the pearl is something else. Obviously, there was no point in...

'Guess that's a big part of the 'keshi' mystery: how to start pearls keeps getting re-invented from a mysterious list of possibilities!

[speaking of old experiments: Linee had a patent for pearls...

Well, just came accross one presentation published from that meeting:

That, or shoestring nucleation...

For the pearls deemed confusing at the buying end [GIA's lab note has a handful of examples deemed as such, looking awfully similar to all others] the question...

What you say sounds allot like Haenni's idea of how some keshi form [above], isn't it?

I wonder whether anyone has a record of the process at all - even in Japanese. What level of detail would be...

I have looked just about everywhere for an account [i.e. observation] of how keshi form, but no one appears to have bothered with them much until just about now. Haenni's report [same as above]...

And they are still at it:

At least for some keshi there are clues to look for already [LINK] and one might imagine that...

Thank you! :)

Talk about perfect timing! :)

Arrgh! [too late...]

Agreed - these are different problems and the addendum is picking the low hanging fruit; I put the link here because this smaller issue also came up way up on the thread (quoted).
