Lovely smokey quartz toned glass cascading necklace by Coppola e Toppo. The piece snaps shut in the front or back depending on how you wear it. The color is really divine. Condition is very good, wearable with care. The metal elements have lost finish or tarnished. Signed. Circa 1960s. Some slight space between clasp and first beads when held up, 1mm. Sort of slides to allow cascading affect. No chips. About 16″ long. On the neck it opens and cascades perfectly on each side.
