My husband purchased this Elvira Bill (Navajo) cuff years ago from "The Rainbow Man" shop on the Plaza in Santa Fe, New Mexico.
He has worn it very few times and has asked me to sell it for him.
It is a heavy sterling silver cuff handmade by the famous Navajo jewelry artist Elvira Bill.  
The total weight of the cuff is 100.8 grams.  Penny weight is 3.5 ounces.
The inside is signed Elvira Bill and stamped sterling.
The inner dimension is 5 7/8" and the outside dimension is 7".  The gap is 1 1/2" and the width is 5/8".  
Will fit up to a 7 1/2 inch wrist.
My husband never had it fitted and it is too large for his 7" wrist (see pictures).
Love this cuff but it is sitting in his drawer for years unworn and needs to find a new home.
Feel free to email me with any questions.
