Turquoise Ring with Rustic Design Size 9

Very rustic hand made sterling silver ring that is set with beautiful natural turquoise with stormy black matrix. The setting has a faint geometric design that shows only in the right light. May show more if it is polished as it has spots of tarnish. 

The shank is hand stamp decorated. The interior has great files marks inside. Face measures 1" by 7/8". Weight: 20.3 grams. No hallmarks. Acid tested.
