Good day! I wonder if someone can help me figure out the Navajo artisan who made this ring. Possibly Bernyse Chavez?, the way the C is stamped next to and a little lower than the B, as shown in the online Amerindien hallmarks reference. Not sure. Ideas? Also, the stone is interesting. Thoughts on what kind of turquoise this might be. The marked price of $50 makes me think it was made a while ago. Thanks!
