Amazing faceted cut crystal beads. You can really see the crisp edges and light play along the crystal. This necklace does have the added weight of crystal as well. There is an alternating pattern of clear and black cut crystal beads with small brass beads in between. They are in great antique condition with little signs of wear. Strung on original double silk string. Box or tongue and groove clasp is a delicate filigree design which is then stamped sterling and with an ornate S as a hallmark that has not been identified as of yet. 

Acid tests positive for sterling silver. 

Necklace measures 17 and 1/2 inches in length.
