Vintage Taxco Mexico Sterling Silver Teardrop Amethyst Screw Back Drop Earrings

Vintage Taxco Mexico Sterling Silver Teardrop Amethyst Screw Back Dangle Drop Earrings Unreadable mark but very similar design to Antonio Pineda, very well made I've seen the same "mirror" / silver backing setting on well-marked bracelets and earrings by Pineda, though the stones very oval shape Bezel set teardrop amethyst is double-sided (its back is not flat), measuring about 7/8" x 3/8" Earrings drop about 1.5" Very good vintage condition with signs of wear and aging
