20" Art Deco, Flapper, Necklace, Antique/Vintage, emerald cut & baguette cut

A antique Art Deco Flapper necklace, rope and chain motif with emerald cut and a baguette cut glass crystals. It's contemporary and timeless. Collect this piece or wear it, it's sturdy and unique. The maker stamped it with an N but my research hasn't turned up the designer's name. Measures, 20" with the 6" pendant (1 1/4" Wide). Silver tone
