Sterling and art glass necklace, Art Deco.
Outstanding... The design, the colors, and the workmanship.
It doesn't get any better than this, it really doesn't. Pictures don't do it justice, they don't capture the dancing sparkle of the carved black stones and marcasite or the subtle glow of the jadite green art glass.
All the stones, probably Czech, are in open backed settings. It is stamped sterling on the clasp. The necklace is 16 3/8" long. You could always use an extender if you wanted more length. The black stones are 1/2" wide with just a hint of silver paint behind the marcasites to set them off perfectly.
Fabulous condition, no issues.
It's a flapper, Jazz Age Beauty!!
