A mineral or other substance often mistaken for gold; mainly iron pyrite.
Something worthless that deceptively seems valuable.
Origin
From the idea that the mineral fools people (especially those who are fools) into mistakenly thinking that they have found gold. Regarding minerals that were named for being deceptive and thus confused with others, compare also apatite.
