Sand dollar pendant locket necklace

Silvertone chain link necklace with lobster claw closure and round locket with cut out sand dollar design. The front of the locket has small holes in the design so you get a peek inside. Magnetic closure snaps shut. Approximately 12 inches long, not including the locket, which is approximately 1 inch diameter. See photos for details and points of measurement. I don't know what metal it is but I'm assuming it's stainless steel or an alloy. It has never tarnished so it's not sterling silver. Approximate weight unpackaged: .9 oz.
