Navajo Turquoise Ring by Tony Guerro Size: 7 1/4

Vintage sterling silver ring that was set with turquoise. It was made by Navajo artist Tony Guerro who was active from the 1970s until 1993. Hallmarked on the back. 

It is a size 7 1/4 and the face measures 7/8" wide. Weight: 6.6 grams. Very pretty loopy design from the size view.
