Southwestern Sterling Silver and Gold Zuni Bear Band Ring

Vintage Southwestern sterling silver ring. It has a silver overlay design with a gold Zuni bear in the center. It is not hallmarked or marked with metal purity. I tested the silver but I don't want to scratch the gold to test it.  Ring is 15mm wide. It is a sizr 9, but it has a split shank and it is adjustable. Split is clean so it was made this way and not broken. Ring is stamp decorated. It has smooth wear. Weight: 5.2 grams.
