This gorgeous necklace features Turquoise disk beads strung with Smokey Quartz faceted ovals and small round Sterling Silver beads. The pendant is a large blue-green Turquoise bead (1" in diameter) and a pyramid Bali bead and a round shiny Sterling bead. My supplier lists the disk beads as real turquoise, while the pendant may be reconstituted. I'm not an expert on turquoise and I don't have complete information- the pricing is based on the cost of the components. The closure is a medium lobster clasp. All findings are Sterling Silver. Overall length is just over 18 inches. An extension chain can be added if requested.
