This stunning sterling silver heavy weight ocean blue Kingman turquoise cuff is made by a Navajo artist Wydell Billie and is hallmarked with his stamp. The inside measures 5.5" and the gap measures 1 3/8". Because of the weight of the bracelet it can not be adjusted. It is ideal for a 6.75-7" wrist at the current size. The widest spot at the stone measures 1.25".
