Iron pyrite, commonly known as “fool’s gold” due to its resemblance to gold, is an iron sulfide mineral. Its value is significantly lower than that of gold, and is determined by factors including specimen size, quality, and aesthetic appeal. While large, well-formed crystals can be sold for decorative purposes, the mineral’s primary industrial use is in the production of sulfuric acid.
Historically, pyrite was a source of sulfur and played a role in early chemical industries. Today, while not a primary source of iron, its importance lies in its continued use in sulfur production. Distinguishing pyrite from true gold remains important for prospectors and collectors alike. This distinction often involves assessing factors like hardness, streak color (the color of the powdered mineral), and crystal form. Pyrite’s brassy yellow hue and cubic crystal structure contrast with gold’s deeper yellow color and malleability.
