$990.00$1,004.85

Tetrahedrite is a copper antimony sulfosalt mineral. Other elements also substitute in the structure, most notably iron and zinc, along with less common silver, mercury, and lead. The distinctive tetrahedron-shaped cubic crystals give the name to the mineral.

The mineral pyrite or iron pyrite, also known as fool’s gold, is an iron sulfide. Its chemical formula is FeS2 (iron (II) disulfide).

Pyrite enjoyed brief popularity in the 16th and 17th centuries. At that time soldiers used it as a means to ignite their firearms, most notably the wheellock. In other words, in this gun, the soldier placed a piece of pyrite against a circular file to strike and produce the sparks needed to fire the gun.

Huanzala is a lead-zinc mine with a 1,200 tons/day capacity, operated by Cia. Minera Santa Luisa and owned by Mitsui Mining & Smelting Co. (Japan). The mine is famous all around the world for excellent pyrite and fluorite specimens. According to well-known mineral specimen importer Rock Currier, the Huanzala mine probably holds the world record with regard to the total tonnage of mineral specimens produced by a single mine. According to Mardani Fine Minerals “Huanzala has been praised as one of the greatest pyrite localities of all time.”
