Iron pyrite, often mistaken for gold due to its metallic luster and brassy yellow hue, has negligible intrinsic value compared to the precious metal. While small, polished pieces might be sold as tourist souvenirs or inexpensive jewelry, its worth is primarily ornamental. Unlike gold, pyrite has a lower density and a more brittle structure. A simple scratch test can distinguish between the two: real gold will leave a golden streak, while pyrite will produce a greenish-black powder.
The historical allure of iron pyrite stems from its resemblance to gold, leading many prospectors on fruitless searches during gold rushes. This deceptive similarity earned it the moniker “fool’s gold.” While not financially valuable in the same way as gold, pyrite serves as a teaching tool in geology and mineralogy, demonstrating the importance of accurate mineral identification. It also has minor industrial applications in the production of sulfur dioxide and sulfuric acid.
