This pair of vintage Coro signed earrings will take your breath away! The yellow center is plastic and when turned they shimmer in different colors. Surrounded by rhinestones (1 earring is missing one stone and is hardly noticeable) they are clip-on variety and probably dates to the 1940's-50's. Size is 1 inch diameter. Coro is a name that has been around since 1902 and they made consistantly beautiful jewelry.
