Vintage layered seed bead shiny necklace black 17"

Really nice layered adjustable one. A little wavy from sitting in a jewelry storage bag but will even out by hanging over a door knob with some weight on it like a small chip bag clip with a napkin or paper towel wrapped over the necklace where the clip will be making contact w/the necklace. 17" long. and an additional 3" extender.
