Royston turquoise is a gemstone mined from Royston Mining District found near Tonopah, Nevada. This rare and unique type of turquoise is known for its rich brown or black inclusions. The host rock complements the blues and greens of the mineral and creates a unique type of turquoise found no where else in the world. This mine was founded in 1902 and is owned by the Otteson Family. The stones that come from this mine are special because it is a small mine and there are limited quantities of these stones available; this makes them highly collectible. The luscious colors of the Royston turquoise calm the mind and bring tranquility into the soul, creating peace and harmony just by looking at it. Artisan made. Total weight is 5.63 grams. How to clean and keep beautiful: 1/2 cup of lemon juice and one teaspoon of olive oil is a perfect way to rid your stone of any filth. Polish your jewelry with this mixture on a dry cloth. Lemon juice's acidity removes tarnish from the silver and the olive oil provides moisture. Do not soak in water, leave in the sun for long periods of time or clean with commercial cleaners of any kind.
