This very unique necklace is choker length 15". It has 3 square jet black squares separating a multitude of rhinestone which is flexible in circle and oblong shapes with rondelle spacers and filigreed goldtone round ball separators. Please look closely at these pictures so you can see what I am trying to explain. Have never seen anything like this but it is certainly a very interesting piece. No markings, old time closure. This is about 1" wide. The square black pieces measure 1" square.
