Physical properties
Hardness: 5.5 to 6.5 on the Mohs scale. Color: Dark grey to black with a metallic luster. Crystal Structure: Trigonal. Cleavage: None. Specific Gravity: 5.3.
Formation & geological history
Forms in diverse environments including hydrothermal veins, sedimentary beds, and as an accessory mineral in igneous rocks, often through precipitation from aqueous solutions over millions of years.
Uses & applications
Used primarily as an ore of iron, in jewelry, carvings, and as a popular tumbled stone for healing and collection.
Geological facts
Hematite leaves a characteristic reddish-brown streak even though the stone itself is typically dark grey or silver. Its name is derived from the Greek word for blood, 'haima'.
Field identification & locations
Easily identified by its distinctive reddish-brown streak test, metallic sheen, and high density/heft relative to its size. Commonly found worldwide.
