Hematite can also occur as a result of volcanic activity. It is paramagnetic in nature. The crystals of hematite which have a steel grey colour and metallic lustre are known as specular iron ore. The scaly ore which is thin is known as micaceous hematite. It has opaque transparency and uneven fractures. Hematite is harder than pure iron ore.
