Pyrite is a common mineral, found in a wide variety of geological formations from sedimentary deposits to hydrothermal veins and also as a constituent of metamorphic rocks. The color of pyrite has sometimes led people to mistake it for gold, hence its nickname "fools gold." Pyrite is easy to distinguish from gold, as it is much lighter. Pyrite is also harder than gold and cannot be scratched with a fingernail or knife.
