The band is marked with the Uncas U and arrow and also is marked sterling.
Size is 7. Circa 1930.
The front measures just about 5/8 of an inch by nearly 1/2 of an inch and a depth of 1/4 of an inch.
The undercarriage has a lovely repousse design. The silver has minor surface wear. The shank is slightly out of round.
The color of this ring is most like a peridot and the yellow-green of natural green amber. Light and easy to wear, but unusual and unique.
