BLUE GEM The Blue Gem mine, which is no longer active, produced almost every
shade of green and blue turquoise imaginable. The Blue Gem mine
site is 6 miles south of Battle Mountain, Nevada. It produced
a great variety of turquoise, from intense blue to deep
green combinations with a hard, irregularly distributed
matrix. It was a prehistoric site and produced thousands of pounds over
many decades. The Battle Mountain or Blue Gem mine, which began
production in 1934 yielded the most valuable Blue Gem turquoise
because of its rich color and hardness. Of the several Nevada
mines that are named Blue Gem, this is the largest and most
famous.
