Vintage Heirloom Sterling Art Deco Carnelian & Marcasite Earrings

The craftsmanship on these earrings is exceptional. It’s too bad the back isn’t visible when wearing! The silver is dolloped with etchings on each layer. They are tiered to allow for maximum light. The carnelian is a rich burnt orange surrounded by a wreath of marcasite. They are stamped 925 on the post, I can see it with the loop with 2 initials that I cannot make out.
