14K Naomi 925 sterling silver vintage Aztec Southwestern earrings Mystic Goddess

Vintage handmade screw on earrings. Southwestern. Aztec mystical sitting Goddess. In excellent condition. The main part is made of sterling silver (no visible stamp, but tested 925 at the jeweler). The screw on parts on the back are stamped 14K Naomi. Not sure how much of the solid 14 karat gold is in there as the spectrometer readings were inconclusive. Could be because of being attached to the sterling part. Or perhaps it is not solid, but gold filled. Naomi is a known vintage jewelry designer, and many of their pieces are valuable and collectible.
