Vintage Glass Stone Bead Necklace, Black White Choker 16", Onyx Quartz

Vintage necklace, 16" choker length, has small square irridescent black beads and round white and gold color beads. The beads are either glass or stone such as onyx & white cat's eye quartz (definitely not plastic - they are cold to the touch). Closes with a barrel screw clasp that does show a little wear, consistent with this being a vintage piece.
