Vintage Native American Navajo Turquoise Sterling Silver Cuff Bracelet

Unsigned, acid tests as sterling silver. The face of the cuff measures almost 2 inches, north to south. It has a 29mm by 18mm turquoise stone. It weighs a solid 47.7 grams. I took a tape measure and measured the inside of the bracelet.

The complete circumference is about 6.5 inches. The 6.5 inches include a 1-inch gap.
