| − | '''Fools gold''' is a kind of [[gold]] found in large despots around lodes of real gold. It is chunky and crystalline, which distinuighs it from real, or ''true'', gold. Fools gold is called "fools gold" because it can easily fool people into thinking it is true gold, until they try to sell it and nobody will buy it. | + | '''Fool's gold''' is the common name of the [[mineral|mineral]] pyrite (iron disulfide, FeS<sub>2</sub>), which, due to its metallic luster and brass-yellow hue is oftenly mistaken for [[gold|gold]]. It can be distinguished from real gold by its crystalline structure and, when handled, sulfuric smell. Occasionally, small quantities of gold can be found in pyrite deposits. |
