Navajo Spider Web Turquoise Shadowbox Belt Buckle Alfred Joe

Sterling silver belt buckle by Navajo artist Alfred Joe. Hallmarked as such on the back.  Set in the center with a fine spider web turquoise stone. Measures 2 1/8" wide by 2 1/2" long. Small loop in back that tells me that this can be attached to a concho belt or a braided leather belt. Loop is 1/2" wide. Weight: 53 grams. Highly collected artist.
