jcobb is correct, the ring is trying for a Native American look - although this one appears more Mexican to me (Native North American Continent anyway)
If you found it in South Carolina , the ring is a long way from home - I'm thinking 1960's -70's that crushed stone (turquoise or malachite ) and epoxy
was all over the place back then . Nice find !
Nice first silver ring there, love the native styled rings! My first silver ring find here had triangles of turquoise and red coral all the way around the band.
I used to sell this type of ring in the early 70's! Crushed inlay looks turquoise!
Silver ring looks like a cast ring. May be Native American but could be Mexican like
Zapotec!
