Vintage Coro Goldtone Blue Glass Prong Set Rhinestone Screw Back Earrings 1 in

Vintage Coro goldtone earrings featuring prong-set blue glass rhinestones. The earrings are signed, with a screw back closure. The metal is goldtone alloy with a rhinestone material. They measure 1 inch in length and have a huggie style. They are signed Coro. I cleaned these up, however there is some tone loss on one earring on the top by the stone. Please see pictures, other than that they're in great shape.
