Hello, my grandmother gave me this ring about 20 years ago. They adopted my mother (who is full-blooded) Navajo from the reservation when she was four. They spent much of their lives working on and just off the reservations doing construction work for the tribe. I'm not sure where she got the ring or how old it is. I can't find the mark anywhere, but just looking for a little history. She passed away about 10 years ago. Thanks!
