Beautiful silver world map necklace. Lobster clasp in the back. This was purchased from a wholesaler, but ModCloth sells a similar one called there’s a map for that. Silver coated metal alloy. The silver is textured, not smooth, and not real silver. This is a fashion jewelry piece. The length of the whole necklace, with the chain opened up and measured from one end to the other, is approximately 20.5” long.
