Hello from Belgium! Anyone that can help me identifying this beautiful ring? My parents bought it in the late 1970 in the southwest. It was presumed an antique Navajo ring with spiderweb turquoise. It is marked on the inside with a bison head, no other marks. I hope the pictures are clear enough. I am curious about the age, the maker and the stone and if there any symbolic meanings. It holds great sentimental value to me and i would love to know more of it’s history.
