Physical properties
Hardness: 5.5-6.5 (Mohs), Color: metallic grey to black, Luster: metallic, Crystal structure: Trigonal/Hexagonal, Cleavage: none, Specific Gravity: 5.26
Formation & geological history
Formed in hydrothermal veins and as a primary mineral in igneous rocks, as well as through sedimentary precipitation in iron formations over billions of years.
Uses & applications
Used as iron ore for steel production, pigments for paints, and in jewelry as polished beads or cabochons.
Geological facts
Hematite is famous for having a blood-red streak when scratched on porcelain, despite its metallic exterior. It was used by ancient humans as a pigment for cave paintings.
Field identification & locations
Identify by its high density and red-brown streak. It is often magnetic if it contains traces of magnetite. Commonly found in massive iron formations in the Lake Superior region and Brazil.
