Pyrite, which is iron sulfide, has been easily confused with gold. Hence, the nickname, Fool's Gold. It gets its name from the Greek pyr meaning fire because it gives off sparks when hit with a metal. It is believed that possession of pyrite attracts money.
In its fine grain form, pyrite can be used as a home décor item in planters, shadow boxes, and zen gardens, or as imitation gold for children to dig up in the sandbox.
