Evaluation Notes: The Blue Gem Mine site is near Battle Mountain in Lander County, Nevada. Originally opened in 1934 as the Battle Mountain mine, the Blue Gem Mine has produced a huge variety of Turquoise, from dark greens to dark blues and everything in between. The Blue Gem Mine is known to be a particularly deep deposit of turquoise, with some mine shafts descending 800 feet below the surface. The turquoise found in the Blue Gem mine is some of the highest quality turquoise found in Nevada. 6.5” wrist 56 grams 2” tall Four Terminal Sterling What I love about this cuff are the unique shapes of the turquoise cluster, the dark background which makes the turquoise pop, and the four terminal thick well made Sterling Silver weight.
