Turquoise Ring - Stamped with a Bull's Head ? Who made this?

[maxiebaby0914]

Hi.. I have a Large Turquoise Ring. It has a stamp on the back of it. It appears to be a bull or bison head. Does anyone know of a silversmith who uses or used this mark on their jewelry? I also was wondering how old it could be. But most importantly, who was the maker? Is this a navajo made ring? Any info would be appreciated.. Thanks..Vikki
