Nevada's original Blue Gem Turquoise Mine is now closed and stones from this mine are highly collectible. Centering a split shank sterling silver cuff, handcrafted decades ago with delicate detail from sterling roped frames to bead balls, a large Blue Gem turquoise takes center stage. Made in USA. One of a kind. 1-3/4" tapers to 3/8"W; 2-1/4" dia.
