STONE: 
The Lone Mountain Turquoise Mine, near Tonopah, Nevada, was one of the leading producers of fine turquoise in Nevada. The turquoise from this mine is mostly good to high-grade and usually in the form of nuggets although there is a quantity of vein material. The turquoise is graded into golden matrix, black matrix and spider web. At present, most of it is cut and polished or the nuggets drilled and polished at the mine, making this is a very collectible turquoise, and rarely available in rough form. It is presently closed.
