Great older Native American ring of testes sterling silver with ropework design and Navajo tears, surrounding a very large turquoise stone, appears to be a natural one although it could be stabilized due to size. Ring is size 4 and 1/2 and is in very good condition. The top of the ring measures 1 and 3/8 inch tall and 1 and 1/8 inches wide. No maker marks. Fabulous ring.
