Good and Early Navajo Turquoise Ring in Sterling Silver Size 7.5

Good and early well made Navajo sterling silver ring. It is C. 1940 and set with natural turquoise. I love the rectangular shape.  It is a size 7.5 and the face measures 7/8" by 3/4" wide. Has a hand hammered shank with cold chisel splits. Weight: 6.7 grams.
