Hi Ms Mills Thanks for posting for me. I do not want to confuse the responders by the modern oyster with a blister pearl DSCN4930-1. This my wife found while we were eating oysters out while we were there on vacation. I know that it is modern. You did not include (at least that I saw) that info in the write up So I wanted to clarify. Thanks again. I look forward to everyone’s thoughts. Thanks in advance. Tom Piscitelli
