HG Blue Gem

Blue Gem is the name of several turquoise claims. The most famous is the Blue Gem mine near Battle Mountain NV. The story is told in Turquoise in America Part Two, 1910-1990.


This cabochon weighs 9.1 carats and measures 2.25cm X 1cm. It is not treated and backed. It is priced at $15 a carat or $136. I have assigned a TG of 81 or HG, High Grade. Blue Gem is hard and does not require treatment. In the clear blue it has a distinctive blue that many prefer to Sleeping Beauty. This stone was cut by and purchased from Jim Elquist who mined the turquoise.
