This is a Native American sterling silver ring. It features a large, oval Malachite cabochon. The stone is surrounded by sterling with three silver balls in a row on the top and bottom of the design.
It measures approximately 1" x .50" and .25" in depth.
Unmarked, the ring acid tested as sterling. The band seems to be elongated near the bottom but does not impede the look or wearing.
From the 1970's, the ring weighs 6g.
