"Fool's Gold"

"Fool's Gold" refers to iron pyrite, a mineral that resembles real gold due to its shiny, metallic appearance. Historically, many prospectors mistaken pyrite for gold, leading to wasted time and effort. While pyrite is visually similar, it has different properties; it is much less valuable and does not have the same economic worth as real gold. The term is also used metaphorically to describe something that appears valuable or promising but ultimately lacks true worth or substance.
