Scallop pearls

I have a customer who has a bunch of scallop pearls that he has been
gathering when he fishes. They are 2.5-4.0mm in diameter. He wants
to do something with them and I want to know more about them before
I commit to something. Any ideas, thoughts, suggestions.

Thank you - Marlene Richey
