This is an early Navajo sandcast wide cuff bracelet with a beautiful yellowish green hued royston turquoise cabochon set in it. Sits at a size 6 on the bracelet mandrel but is very wide. The inner circumference of the cuff is 5.4 inches with a gap of 1.6 inches. And it is 2.5 inches from one side to another.
So looks like it goes to a size 6.5 because of how wide it is. Unmarked, Most early Native pieces are unmarked.
