Tyrone
Tyrone turquoise was mined outside of Silver City in the southwestern area of New Mexico. As with many turquoise mines, its original purpose was for copper mining.Turquoise is considered a secondary mineral of a copper mine, and because of the money and scale of operation is for the copper, these companies see turquoise as a waste product and it ends up in the tailings. Rarely, some copper companies will allow people to pick turquoise out of these rock “refuse” piles. In the early 1980s, when the Tyrone mine owner, Phelps Dodge, employed a new extraction method of crushing and acid wash, this process destroyed any turquoise within the copper ore. Because of this, Tyrone turquoise has not been mined since then.

White Buffalo
White buffalo turquoise has been referred to as “White Buffalo” in US mining and trading circles for over fifty years. Most participants in these circles do not use the term “White buffalo Turquoise” at all, as the stone is not truly turquoise. Because White Turquoise contains no copper and lacks a blue coloration, it is technically not turquoise at all. The main mineral in white buffalo stone is Calcite. But depending on the crystalline structure of the Calcite, it morphs into minerals called Dolomite or Aragonite. It is a softer stone than turquoise and is typically white with black or brown vein patterns. White Turquoise is typically found in the southwestern United States, particularly in Nevada and Arizona.

Variscite
The Variscite Turquoise comes from Fairfield, Utah. This mine was opened in the 50s, the Utah Variscite that came from this mine was extremely rare and had inclusions of Crandelite, Wardite and other rare minerals. A lot of this material was sold as specimens as it was too beautiful with all the other minerals in it to cut it up. This particular type of Utah Variscite is very hard to came by. The real allure of this Utah Variscite to me is the mix of the Variscite, Crandelite, and Wardite which give the stone a wonderful picture
