A nice pair of sterling silver and green stone screw back earrings from Mexico. They consist of a lacy sterling setting with screw backs into which green stones are bezel set. The stones may be onyx or glass, but either way they are a pretty color and without any chips or cracks. The backa are marked quite faintly with, "FSI", "Hecho En........." and what looks like, "Sterling". (I guarantee that they are sterling silver).
They measure 7/8" across and are about 1/4" deep.
Thanks for looking!
