Dramatic Point Up Square Black Glass and Rhinestone Choker Necklace is in a class by itself. The point up black glass pieces are 7/8 inch square. The edges are rows of pave set rhinestones. The closure is 2 horse shoe overlapping pieces with pave stones, and a clip closure for adjust-ability. It measures 15 1/2 inches wearable, adjustable downwards. Very sleek for evening, very cool for day. A great piece to add to your vintage collection.
