Turquoise from Nevada's Blue Diamond mine was first sourced in the thirties and is rarely found on the market other than in vintage jewelry such as this. Featuring hand-stamped designs, this coin silver cuff is centered with a stunning example of this highly sought turquoise and its uniquely characteristic dark matrix. One of a kind. Made in USA. 1-1/2" tapers to 5/16"W x 2-3/8" dia.
