Pyrite, also called iron pyrite or fool’s gold, a naturally occurring iron disulfide mineral. The name comes from the Greek word pyr, “fire,” because pyrite emits sparks when struck by steel. Pyrite is called fool’s gold because its colour may deceive the novice into thinking he has discovered a gold nugget.

Pyrite is a very common mineral, found in a wide variety of geological formations from sedimentary deposits to hydrothermal veins and as a constituent of metamorphic rocks. The brassy-yellow metallic colour of pyrite has in many cases lead to people mistaking it for Gold, hence the common nickname 'Fool's gold'.

The only common mineral that has properties similar to pyrite is marcasite, a dimorph of pyrite with the same chemical composition but an orthorhombic crystal structure. Marcasite does not have the same brassy yellow color of pyrite. Instead it is a pale brass color, sometimes with a slight tint of green.

Pyrite is Fe2S, an important example of a sulfide mineral. Often known as "fool's gold", it has a shiny metallic gold color. All the samples shown here are on display in the Smithsonican Museum of Natural History. This sample has a maximum width of about 15 cm and is from Navajun, La Rioja, Spain.

Marcasite is a polymorph of pyrite which means that it has the same chemistry as pyrite but a different structure and, therefore, different symmetry and crystal shapes. The marcasite/pyrite polymorh pair is probably the most famous polymorph pair next to the diamond/graphite pair.
