Pilot Mountain
The Pilot Mountain mine is located in northern Nevada, in Mineral County, near the town of Tonapah. It is still producing and is worked by one family. The stone is highly admired for its deep blue-green colors. In addition, it can show light blue to dark green colors on the same stone. This graduation in color is unusual and makes the turquoise very collectible. The matrix is black to golden brown. Although sometimes a little porous, or pithy, Pilot Mountain is a hard stone and takes a good polish.
