Color
The color of a mineral does not tell everything.Sometimes two different minerals are the same colors.Just like Pyrite which is also known as fool's gold.Pyrite looks exactly like gold but to tell the difference you must do the streak test.

The streak test is a mineral test that you take porcelain tile and rub the mineral against it.The mineral would leave a color like black,brown,green,blueand so on.Pyrite leaves a blackish greenish color when you rub it on porcelain tile.
