A black beaded necklace in excellent vintage condition. A lovely Black Glass, beaded necklace. It is marked on the clasp "925" which is sterling silver or 925/1000 of silver content. I love the clasp as it is a hard working and strong magnet that keeps this attached, nice knots between each onyx glass or black bead. The beads are geometrically cut and not a simple circle. Stunning and can be worn casual or for dress up~ The stunning necklace is 22 inches long with beads that are 1/2 inch wide. From an Estate of jewelry that literally, most pieces were never worn. Just purchased and admired. Perfect, clean and elegant.
