Sterling Silver Navajo Native American made turquoise ring.

This beauty has been signed by the artist. It is sterling silver, and natural turquoise. It’s a size 6 1/2. I bought it from an older Native American woman who no longer wore her jewelry. I’ve had it for about 6 years. It’s in perfect condition! With Native American jewelry, the silver should not be cleaned, other than lightly with a clean cloth as it will effect it’s value.
