The Royston Turquoise Mine is located within the Royston District located approximately 20 miles northeast of Tonepah, Nevada. Active mining of Turquoise began in the Royston District about 1904 and shortly after three claims were filed; Royal Blue, Oscar Wehrend and Bunker Hill. In later years came the Easter Blue and then the current mining region, "The Royston Mine" when Lynn Otteson came to Tonopah in 1958. Royston Turquoise was originally a tunnel mine, it is now an open pit. The Royston Turquoise Mine is no longer mined on a large scale and the Turquoise is becoming very scarce.

Turquoise is a sedimentary formation that is formed when moisture (rain or snow) filters down through mineral rich soil on the upper crust of the earth. This soil must contain the precise amounts of copper, aluminize sulfites and iron to create the combined liquid that siphon's down into voids below the surface of the earth.

Royston Ribbon Turquoise is from the Boulder turquoise mine in northeast Nevada. But Royston “Ribbon” Turquoise should not be confused with "Royston Turquoise". Royston Turquoise originally consisted of four old Turquoise claims located within the Royston range: Bunker Hill, Easter Blue, Oscar Wehrend, and Royal Blue. The Royal Blue mine was responsible for the majority of the turquoise mined in the area and is often referred to as Royston Royal Blue.

Royston Ribbon Turquoise, on the other hand, forms in the Boulder mine also in Nevada. In fact vein Turquoise appears in many boulder mines. The turquoise develops in amazing stripes or ribbons -- and it is up to the stone cutter or lapidary artist to enhance the beauty of the stone by optimizing the placement of the ribbon. This also effects the price of the material.

It was originally discovered in the 1970’s by a herder who stumbled upon a vein of turquoise on the hillside. Since then production of this unique type of turquoise has been small because of how remote the mine is. This makes Boulder Turquoise valued for both its beauty and rarity.
