This is a sterling silver and turquoise ring. Based on the design, it could be either Native American or Mexican. It is simply marked 925. The ring is a size 6-1/2. The top measures just over 1 inch long. There is a fissure or crack across the center of the turquoise. I do not know if it goes all the way through. Otherwise, the ring is in good condition but does have an age patina and may need cleaning or polishing. Please let me know if you have any questions. Thanks for stopping by.
