Physical properties

Hardness: 5.5-6.5; Color: Steel-gray to black with a metallic, sparkling luster; Crystal structure: Trigonal; Cleavage: None; Specific gravity: 5.26; Streak: Reddish-brown

Formation & geological history

Formed as a primary mineral in iron formations through hydrothermal processes or during the metamorphism of iron-rich sediments. Found in Precambrian banded iron formations around 2.4 to 1.8 billion years old.

Uses & applications

Primary ore of iron; also used as a polishing agent (jeweler's rouge), pigments in paints, and for ornamental purposes and jewelry (beads and cabochons).

Geological facts

The name hematite is derived from the Greek word 'haima' for blood, due to its red streak color. Specular hematite contains thousands of tiny mirror-like mica-like flakes that create a brilliant sparkle.

Field identification & locations

Identify by its distinctive reddish-brown streak (even if the rock looks black) and the shimmering metallic flakes. It is commonly found in Michigan (USA), Brazil, Australia, and South Africa.
