How do you identify fool's gold?

Pyrite has a metallic luster and a brassy-yellow color. One way to identify it as pyrite would be to perform a streak test by sliding the sample across an unglazed tile with a little bit of pressure. Pyrite will leave a greenish black streak on the unglazed tile. After exposure to flame, pyrite will have a slight sulfur odor due to its chemical composition. Pyrite will also spark when struck against steel. Pyrite has an uneven fracture and is brittle when struck. The mineral may appear as cubic in shape, or often octahedral with crystal face striation. It has a specific gravity of around 5.0, which will seem heavy to a comparably sized rock. Finally, pyrite has a Mohs hardness of 6.0-6.5.
