Vintage Coro Screw Back Earrings with Faux Pearls and Purple Crystals

These are so pretty! Dainty filigree style gold with tiny faux pearls and purple stone. They are screw back and likely from the 1950's. They are in very good shape however on one earring the center purple stone was put on at an angle. This is an original flaw and not damage, but thought I should mention it.
