Vintage Native American Navajo Sterling Silver Blue Turquoise and Coral Ring. The ring has substance to it and feels comfortable on the finger. The Coral and Turquoise are in great condition. It looks like this ring was sized up by the previous owner. I think the 925 mark has been polished off. The ring tested to be Sterling. Finger size 9.5. It measures 1 3/16 Inch Long X 9 1/16 Inch wide. Weighs 8.2 Grams. Very Good to Excellent Condition.
