Jacobsite-Magnetite Series. Magnesioferrite-Magnetite Series. Magnetite is an important, strongly magnetic iron ore, along with hematite. Nanoinclusions of magnetite crystals cause the iridescence of Rainbow obsidian (Nadin, 2007). Extremely thin layers of 200-nm octahedral crystals of magnetite give some basalt surfaces an iridescent sheen (Nadin, 2007).

List Common Oxide Minerals - Mineral Processing & Metallurgy

When testing for hardness by scratching the mineral with the point of the blade, a magnetic mineral will form a fringe around the point. But caution is necessary here; if the mineral is about the same hardness as the blade or harder, the fringe may be made up of bits of steel from the blade. Magnetite is a common ore.
