This piece is by Navajo artist "Willeta." It is signed on the back. This stone is FABULOUS! I have never seen one quite like it. It has an amzing high gloss on it. It sets high in the sterling silver stamped bezel holding the stone. The side of this cuff make it unique as well. They are sterling silver scallop designs. This cuff measures approximately 5 1/2" on the inside with an adjustable opening of 1 1/2 inches. It is approximately 1 1/8" wide at its widest point, the center.lThis is a very adjustable cuff! It is hallmarked "Willeta" and Sterling. It weighs 23.9 grams.
