Vintage French jet black glass bead necklace - 51” long

Elegant Art Deco-style mid-century French jet black faceted glass necklace measures 51” long and can be worn doubled (or even tripled if you are more petite - I'm 5'1" and this necklace fits me perfectly). The necklace is hand knotted between each 7mm bead and closes with a brass barrel clasp. Very good vintage condition. Length (approximate): 51” (end-to-end unclasped) Bead diameter (approximate): 7mm
