No, not (yet). Are there any pictures you could put up on your
website. I would very much like to see those tiny black grains
of sand that are so tightly packed and glued together as you
state. They m a y (speculation only so far!) represent highly

Certainement Bernd!
There are 4 pictures waiting for you (and whomever else is interested). I hope they are good enough but I am not so sure.
2 are of a Wabar pearl with black grainy interior.
And 2 of another pearl showing WHITE interior.
Now I am very curious to see what explanation there can be, particularly the 2nd one.
And what exactly do you mean by "de-vitrify" ?
