Antique French Art Deco sterling silver genuine chrysoprase marcasite necklace

Excellent 1920s condition, shows a gorgeous darkened oxidation throughout. This Art Deco piece features a vivid green genuine chrysoprase cabochon, emerald green glass baguette rhinestones, and several faceted marcasite gemstones, none missing. Stamped faintly with the French boar’s head mark on rear of pendant and on spring ring. There are a couple of other obscure marks on pendant that I can't make out. Chain measures 18" long. Clasp functions perfectly. Please see photos for pendant measurements in inches. Tags: semi precious semiprecious faceted jewels jeweled gems gemstones embellished embellishments
