Pyrite, a metallic mineral, is composed of Iron and Sulphur atoms bound together in the ratio of 1:2 (FeS2) and falls in the Sulphide minerals category.
Pyrite has a metallic luster and a pale brassy-yellow hue, providing it a superficial resemblance to Gold. During old mining days, the naïve gold prospectors mistook little pieces of pyrite for gold, due to which the mineral was nicknamed ‘Fool’s Gold’. Its opaque crystals often grow in a cubic habitat displaying isometric symmetry. Although it is known for its brassy yellow color, Pyrite can sometimes display greenish-black streaks and when ground into powder, its color appears to be a rich greenish-black.
