Navajo Spencer Blue Gem Turquoise Cuff/Bracelet

Gorgeous Navajo bracelet, given to me by a family member from New Mexico over a decade ago. I've never worn the bracelet and it appears to be in great condition. It fit my wrist diameter of 7 inch. Since silver is relatively malleable, the bracelet is therefore adjustable. It's marked on the back but the inscript is very difficult to read. Weights 16 grams. See photos for dimensions.
