Hematite is an iron oxide mineral with the formula Fe₂O₃, known for its often metallic lustre and colours ranging from steel grey to black, sometimes with reddish-brown tones. It crystallizes in the trigonal system and can occur in a wide variety of forms, including well-defined crystals, crystallized groups, compact masses and metallic-looking surfaces. Its red to reddish-brown streak is also one of its best-known identifying characteristics.
The hematite specimens currently available are displayed a little further down this page, with their photos and videos.
Hematite: appearance, crystallization and characteristics
Hematite generally has a hardness of 5.5 to 6.5 on the Mohs scale and a relatively high density of around 5.3. Depending on the conditions in which it formed, its appearance can vary considerably from one specimen to another, with bright crystal faces, crystallized aggregates, more massive formations or surfaces with a metallic lustre.
Visible colour alone is not always sufficient for identification, as some hematite specimens may appear almost black. Its red to reddish-brown streak can help distinguish it from several other metallic minerals. The diversity of its forms and appearances also makes hematite an interesting collectible mineral with a wide variety of specimens.
