Fool's Gold is a common nickname for the mineral pyrite, which has a shiny, metallic luster and a pale brass-yellow color. It often resembles real gold, leading to confusion among prospectors and miners. Pyrite is composed of iron and sulfur and is found in various geological formations, including sedimentary and metamorphic rocks. Despite its misleading appearance, Fool's Gold has no significant economic value like real gold. However, it is used in some industrial applications, such as the production of sulfuric acid. Additionally, pyrite can be a source of iron and is sometimes collected by mineral enthusiasts for its unique beauty.
