  • University of Minnesota’s Mineral Pages: Calcite

    Although other metallic minerals may mimic magnetite’s 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.
