Navajo Snake Eye Turquoise Ring in Sterling Silver Adjustable

Vintage Navajo sterling silver snake eye turquoise ring with an open shank that makes it adjustable. Right now it is a size 9. It was constructed with the overlay technique. It greatly needs to be cleaned with a soft brush. I leave pieces as found in original patina, but this piece needs cleaning as it has verdigris where the bezels are soldered because of the copper in the solder. 

Measures 1/4" wide. Nice patina. No hallmarks. Acid tested. Great for stacking.
