Although other metallic minerals may mimic magnetiteâs color, luster, hardness and specific gravity, magnetite is the only common mineral that is magnetic. So a magnet is usually all that is needed to identify its presence. Magnetite crystals usually only occur when magma cools slowly enough for crystals to form and settle out of the magma.
Generally, a mineral is a naturally occurring solid with a crystalline structure. This is where it gets a little tricky. Halite or table salt is a mineral. Sugar is a crystalline solid but comes from plants, sugar cane or sugar beets. This classifies it as an organic compound and so is not a mineral. Coal on the other hand also comes from plants (organic) and is generally considered a mineral.
