This is a nice, thick, finely-stamped concho—like in "concho belt." In fact, it was once part of an obviously very nice concho belt, and was made into this nice pendant. Not counting the bale, it is 2 and 5/8th's-inches long. It is 2 and 1/8th's-inches across the girth. Weight is 40-grams, or 1.4-ounces. The included "pearl" chain is 4mm thick and 20-inches long and is a costly addition these days. The concho is not hallmarked because it was a concho in a concho belt! The force required to stamp it at this time would cause the force to deface the other side. Now where are the rest of those conchos from that belt??
