The mineral pyrite (/ ˈ p aɪ r aɪ t /), or iron pyrite, also known as fool's gold, is an iron sulfide with the chemical formula FeS 2 (iron(II) disulfide). Pyrite is considered the most common of the sulfide minerals. Pyrite's metallic luster and pale brass-yellow hue give it a superficial resemblance to gold, hence the well-known nickname
Gold is a heavy metal in a group known as the transition metals. Gold is also known as a precious metal (as are platinum and silver).
