Abalone and Cone Shell Necklace with black base background Has a button loop closure. Pendent is about 2.25 inches round. Comes on 17-18 inch cord. Beautiful Iridescent colors, the Abalone shells in this pendant radiate vibrant and luminescent colors of the rainbow as they move in the light. I purchased this in Cozumel Mexico. I bought about 15 different necklaces to give to friends and family back home. It was hand assembled by the locals. I go there every year for scuba Diving. Necklace is pre-owned but likely never worn.
