This Native American (most likely Navajo) ring is the largest I have seen. It measures 2 3/16" tall and 1 5/8" wide. It is interesting to note that because of its large size, the maker had to solder two pieces of silver together to create the backing. It is set with round and pear shaped natural turquoise stones. The ring is size 7 1/2 but can easily be sized up or down. Made circa 1950; found in Arizona.
