  • Pyrite

    The mineral pyrite (/ p a r a 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 of fool's gold.
