This is an elegant and very dainty circa 1920's sterling silver marcasite necklace which features as focal point a four petaled floral piece from which hangs another larger five petaled flower. Each floral piece holds an oval bezel set genuine chrysoprase stone in the center. Beautifully made with highly detailed workmanship. Probably German in origin, this is a wonderful example of Art Deco marcasite jewelry, classic and timeless! The necklace length is just under 16". The 4 petaled flower is 3/4" by 3/4" and the 5 petaled flower is 1" by 1"." The chrysoprase stones are in great condition and all marcasites are intact, non replaced. I cannot find a hallmark but piece has been tested as sterling silver. Box and tong clasp shut firmly and has an additional security hook. Natural patina build up over the years which could be buffed with a polishing cloth to add a little shine if desired.
