Vintage Coro Green Rhinestone Screwback Earrings

Cute and simple green rhinestone earrings by Coro.  Each earring was created with three round stones and a navette.  All are prong set in goldtone.  They are screwback earrings.   These earrings are in good vintage condition with some wear to the gold plating and peppering that can be seen if you look closely at the stones (see photos).
