French jet black glass bead graduated necklace

This sparkly 1980s French jet black glass faceted bead necklace features graduated rondelle beads instead of the more common round beads. The necklace is hand knotted between each bead (please note there is a little “play” between the knots and the beads, which does not detract from the overall appearance of the necklace). The necklace measures 22” plus a 3” extender and closes with a secure silvertone lobster clasp. Very good vintage condition. Measurements (approximate): Necklace length: 22” plus 3” extender Bead height: graduated from 16mm in front to 7mm towards the clasp in back
