Real Pearl in Shell Pendant - Very Old - with Ornate Silver

This is a really unique & beautiful Pearl in shell pendant. I’ve never worn it or put it on a chain or cord; I’ve kept it carefully packaged and would love someone to have who might really appreciate it. I don’t think the pics do it justice. I don’t know if the ornate silver piece is sterling. Not stamped but I think this is pretty old. See images for approx. measurements. Please ask any clarifying questions prior to purchase ⚡️
