Green Turquoise Sterling Navajo Native American RingSz7

Likely on the older side of things for Native American jewelry. The green turquoise has aged and has some missing segments, breaks, etc.

It is signed LS on the backside. My best guess is that this is Navajo, by Lula Mae Stago.

The length of the face of the ring is 1 1/2 inches. 

This ring is a size 7.

It weighs 11.3 grams.
