The Blue Gem Turquoise Mine was located in the Copper Basin area southwest of Battle Mountain, Lander County, Nevada, USA. Production of this turquoise mine started about 1934 and continued until the 1970's. Blue Gem Turquoise is some of the finest turquoise ever found, and unlike most turquoise mines, (in which the majority mined is chalky and only usable if stabilized) most of the turquoise found there was of gem-quality. There is a distinctive aqua color that some people associate with Blue Gem turquoise, although it produced a great variety of colors, especially when intense blue was combined with deep green in one stone.
Very little large material ever came out of the Blue Gem Turquoise Mine, the majority found was small 1mm - 4mm "feeder" veins.
