Beautiful work that speaks for itself! A better sense of scale would be great (MM for top of tee for example). Also, do you know the source and mollusk species? It appears to be two coin sacs in the process of joining.

The JCK article ends: Qui a finalement évalué la perle ? According to the article, the value would be determined by a proposal to purchase. I say SELL!!!

Jeg, your posts are more than the pearls themselves (which are beautiful), they communicate your passion and show everyone that they have no business hiding in jewelry boxes, and that the smallest collection can be made larger through combinations. As a guy I can relate by remembering salesmen...

Nonetheless, willingly-led humans are everywhere, as are their Pied Pipers.

I assume Mr. Lee has the same question.

This thread was brought to the attention of the University of Granada faculty and the associated international biomineralization research team. It has reawakened interest in studying the nature of those pearls with vortical growth patterns, and to readdress the rotational mechanics involving all...

Recently a forum was created called 'Pearl Diver' for scientific and/or diversionary posts such as this one. But those Tokkis shocked me into realizing that the AI that created the image in THIS POST was thinking Tokki all the time! Scary!

Douglas, belatedly seeing this. Were these the folks at PBTB in May? Unfortunately we didn't make it by their table. Question 1: Given the 35% rejection rate, are they getting any keshi? Question 2: Is there any thought of removing the protein deposits, following the precedent of polishing...

Does Ravi have a pearl trade market for his shells after all?

Taking nothing away from the technological achievement, this is size for its own sake, like American cars in the mid-20th century before the oil crisis. Will fins be next?

Clearly dating myself. But it bounces much better.

What exactly are the labs being asked (or told) to certify?

Now that's really shot down the market for dye cast or 3D bead prints from shell powder (from another thread). Next the beads will be hollow. Ping-pong pearlomacy, anyone?

Round, Drop, Button, Circle. Symmetry in pearls is the foundation of their appreciation and historical value. So much so that the cultured pearl industry went to great extremes to give them a head start and helping hand with round bead nuclei. But even with the head start the mollusk must...

So Ravi was just wondering if there might be a commercial outlet for the small shells, other than fertilizer. Seems he's out of luck!

To continue with the baseball analogy, when facing a pitcher with a delivery as fast, accurate and varied as yours the hitter is lost if he tries to guess. He can only react and trust his instincts. It's a privilege to follow your passion and see the superb results!

More Castillo (Mariners' pitcher Luis): "Keep them guessing."

Subscribes to the 'less is more' aesthetic. No whiplash this time. A pattern is emerging (until it is broken).

I wonder if Ravi's species-specific inquiry has any merit? Would the matrix material in 3D-printed mussel shell beads make them incompatible? The powder itself is not a mystery, it's mass produced as a soil pH amendment for agriculture and for the poultry industry.

This thread just came to my attention due to a reorganization of the forum threads today. The poster refers to his concept of producing custom beads from shell powder, in the manner of 3D printing. Having just seen a 60 Minutes report on plans for 3D-printing a moon base, consideration seems...
