This unusual necklace is vintage circa 1940s or 50s. It is fashioned from sterling silver and turquoise beads and is a signed Taxco Mexico piece. The necklace measures 22 inches long, the turquoise beads are about 12 mm each and the brushed sterling pieces measure 1 1/6 x 3/8 inches each. The clasp is stamped Sterling, 925, Taxco, Mexico and has a script ERE on it. The condition is very good with no problems. I have polished the sterling pieces a bit as it was nearly black when I acquired it.
