Sterling Silver Native American Signed Bracelet

A beautiful Sterling silver bracelet with a large orange colored natural stone,. This bracelet is marked sterling and the initials Ct. My research identifies this maker as Caroline Taw Angyaouma 1906-1996. She was the wife of the famous Hopi Jeweler, Ralph Taw Angyaouma. Open back space is 1 3/4 inc. Would fit small to medium wrist. Stone is slightly under 1 inch long and 3/4 " wide. Very nice bezel work. I believe the stone to be an agate, but I am not a jeweler. Excellent condition!
