Vintage Southwestern Turquoise and Black Stone Inlay Ring, Size 8

Vintage Southwestern Turquoise and Black Stone Inlay Ring, Size 8. Vintage- Pre-owned by me but haven’t worn it as much as I’d like. Trying to downsize some of my jewelry if I can! My loss is your gain. Good Condition. Circa -1990’s era, specifically 1994 as marked on the inside of the ring. Was made in New Mexico. Gold tone like antique brass color. I do not know the metal materials used to make this ring. Unique three diamond shaped design on the band with one black diamond shape design at center and two crushed turquoise inlay- one on each side. Etched design on band. Stamped COP94.
