Huge Vintage Navajo sterling silver ring. It is set with a stunning natural turquoise stone that I attributed to the old Carlin Mine. This stone is a perfect blue filled with black chert matrix. It is a reverse look with the turquoise forming the spider web around the chert, with is very in line with how turquoise formed in the earth. 

Measures 1 1/2" long by 1 1/8".  Weight: 26.2 grams. Approximate size is 9. The shank is somewhat oval due to the large size of the stone. 

Bezel is hand notched and t5he band has smooth wear. Super nice collectible piece.
