22097 - Beautiful 3.23 Inch Pyrite Crystals on Calcite from El Hammam Mine - Morocco Tetragramma Etymology: after cyril AThe 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. 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. The color has also led to the nicknames brass, brazzle, and Brazil, primarily used to refer to pyrite found in coal.
