How can you tell fool's gold from real gold?
Pyrite, called fool's gold, shines like brassy gold but is a different mineral. Real gold is soft enough to dent with a nail, while pyrite is hard and brittle, and may form tiny cubes. Gold leaves a yellow streak, and pyrite leaves a greenish-black one. Gold is also much heavier for its size. Rock hounds use these tests to avoid being fooled.
