turquoise is from a group of mines near Tonopah, Nevada.
The Royston District is one of Nevada’s better
known turquoise-producing areas with the Royal Blue,
the Bunker Hill, and the Oscar Wehrend being the three
most important mines. Royston turquoise can be unbelievably
beautiful. Colors vary from different shades of green,
dark sky blue to green and blue together in one stone.
Matrix can be a beautiful brown and the best Royston
is equal to that found in any American mine.
