Zuni Bear Band Ring in Sterling Silver with Turquoise

Vintage sterling silver Southwestern ring. The design of the Zuni bear was executed with the overlay technique. It is inlay set with two turquoise stones. Size 8.75 and at center front it is 3/8 grams. Weight: 5.3 grams. It has no hallmarks. I suspect that this ring has a higher silver content than 925 sterling is it is smooth and bright white. Has wear from age.
