This admirable collar style necklace is a hand-made piece of fancy jewelry containing 100% genuine Russian amber in various hues. The amber neck-ware is lightweight and very comfortable against the skin (stones are rounded on one side and flattened on the other side for added comfort). The small beads are about 1/4" long and the large beads range in size from about 1" to 1 3/4" long. Necklace fastens by barrel screw twist-in clasp.
