Vintage sterling silver & turquoise ring. It has the construction of a ring that was made on site at an Indian trading post shop in the Southwest. The stone is pale turquoise and appears to be natural. There is old white silver polish around the edge. I left it in original patina, but this can be cleaned out with a little soft brush. Marked sterling on the back. Weight: 4.5 grams. Size 9 Fred Harvey era.
