Physical properties

Formation & geological history

Formed in hydrothermal veins, metamorphic rocks, and as a primary mineral in igneous rocks. Often found in Banded Iron Formations (BIFs) dating back 1.8 to 2.4 billion years.

Uses & applications

Primary ore of iron; also used as a heavy media for coal separation, in radiation shielding, and as a popular ornamental stone for jewelry and decorative specimens.

Geological facts

The word 'Hematite' comes from the Greek word 'haima' for blood, due to the blood-red color of the mineral's powder and streak. This specific variety, Specularite, is named for its high reflectivity mirroring small mirrors.

Field identification & locations

Identified by its distinctive metallic glitter and a cherry-red streak when rubbed on unglazed porcelain. Commonly found in major iron-mining districts like the Lake Superior region in the USA, Brazil, and Australia.
