No real news, just another quick summary of the matter from a top lab, including a sad note on available testing (or lack thereof).
I'm attaching the document because the article ends with an invitation to submit pearls for the lab to learn from - which seems to fit here. What might they make of the copper freshwater pearls?

SSEF has quite some reputation for providing 'paper' for important pearl jewelry. Which, of course, is prominently stated in their public communication. Why not!
