Early Navajo Turquoise Raindrop Ring in Sterling Silver Size 6

Early Navajo sterling silver ring set with blue turquoise. The ring is a size 6. It is of simple design with large hand dropped raindrops on the points of the stone. The shank is cold chisel split and on one side the splits are broken, see photo. This makes it adjustable. It is wearable this way but it is indeed damaged so it gets to be offered in the $39 collection. 

Face measures 1 1/4" long. Weight: 7.4 grams. No hallmarks. Acid tested. C. 1935.
