Great Pyrite from Peru

A pyrite from Peru with a natural golden luster. The crystal structure shows clearly recognizable, geometric cubic shapes, almost as if polished, yet it is a purely natural product.

Pyrite is an iron sulfide with the formula FeS₂ and a Mohs hardness of 6.25. Its cubic crystal structure creates these blocky, often almost perfectly rectangular crystals, which have fascinated collectors and gold prospectors alike for centuries.

Peru supplies particularly beautiful pyrite crystals worldwide from the mineral-rich mining regions of the Andes. The shiny surface and striking geometric shape make pyrite a classic display mineral.
