| What is it? Some kind of silicone? It would encase the pearls in an
impenetrable coating of some kind?
I am most curious how it would change the pearl to have a coating like this. Change the pearls "interactions" with the air, say.
For that matter, I wonder how pearls like to be locked up in a little plastic tube for a long time. Would this kind of coating be similar in effect?
