Royston is a turquoise mine located within the Royston District near Tonepah, Nevada. The Royston District consists of several mines including Royston, Royal Blue, Oscar Wehrend and Bunker Hill. The mines in this district were discovered as early as 1902; in fact, Royston is the oldest patented mine in Nevada. While Royston is considered an active mine, it is a very small operation. The miners go to the mine only twice per year. Royston was originally a tunnel mine, but is now an open pit. Royston is a good producer of high quality stones. According to one of the current miners, Royston turquoise is known as “grass roots,” which means the best deposits are found within ten feet of the surface.

Royston stones are often two-tone, displaying both dark and light green and sometimes blue. Royston has a heavy matrix ranging from dark brown to gold in color. This matrix makes for beautiful combinations with the color variations of the stone. Royston turquoise is considered very collectible and a good investment.
