Vintage Navajo sterling silver ring. It has orbs in the center and is set with two small turquoise stones that may be from the Bisbee Mine. The largest orb in the center has a red spot. I tried to remove it and it will not budge. I tested it and it looks like copper but tests sterling. Upon close inspection it is a solder smear from when the orbs were soldered in place. Solder has more copper than 925 silver. Size 7 3/4. The shank is hand hammered. Face measures 3/4” long. Weight: 3.6 grams.
