The mineral pyrite, or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals.
The metallic luster and pale brass-yellow hue give it a slight resemblance to gold, hence the well-known nickname of fool's gold.
