ABALONE & MOP SCREW BACK EARRINGS CIRCA 1950 s

These are absolutely beautiful they do have a screw back they are sterling lovely, lovely designed earrings who knows who made them got them way back in the day circa 1950s mom stuff is old gorgeous and very highly collectible. You don’t find hardly any of these with the screws and I think it could be black. Onyx mixed in there as well, but don’t quote me because I’m not a jewelry expert by any means just a jewelry, lover, and jewelry seller
