What is "Fool's Gold?"

Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well.  Compared to actual gold, these minerals will flake, powder or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead.  In addition, actual gold will leave a golden yellow streak when scraped on a peice of unglazed porcelain.  Pyrite and Chalcopyrite will leave a dark green to black streak and the common micas will leave a white streak.
