Pyrite

Cube seperate and cube in parent rock
Location: Spain

 It may be hard to believe but this cube is really unprocessed! Pyrite is an iron sulfide (FeS2). The mineral is an important iron and sulfur ore. It crystallizes in striking cubic crystals, sometimes even in incredibly exact cubes, like this one. Due to the characteristic golden sheen, pyrite is also called 'fools gold' because it is sometimes mistaken for gold.

 The name pyrite is very old, derived from the old Indo-European word pyr (fire, eg pyrotechnicus for fireworks artist or the English pyre: pyre), because one could make sparks by striking pyrite against flintstone or iron.

Important locations alongside Spain are Peru, Bulgaria, Kosovo and the island of Elba. It is one of the few minerals that can be found in small specimens, even in the Netherlands (Veluwe and Winterswijk).
