Physical properties
Hardness: 5.5-6.5 on Mohs scale. Color: Metallic dark grey to black with reddish undertones. Luster: Metallic to submetallic. Streak: Characteristic reddish-brown streak. Crystal system: Trigonal.
Formation & geological history
Forms as a primary mineral and as a precipitation product in sedimentary, igneous, and metamorphic environments, often in banded iron formations.
Uses & applications
Primary ore of iron, used in steel manufacturing, pigments, radiation shielding, polished tumbled stones for jewelry, and crystal healing collections.
Geological facts
When ground up or scratched, hematite leaves a distinctive rust-red powder streak, which gave it its name from the Greek word 'haima' meaning blood.
Field identification & locations
Identify by its high density/weight for its size, metallic luster, and reddish-brown streak when scratched against unglazed porcelain. Commonly found in Brazil, Australia, USA, China, and South Africa.
