Physical properties

Formation & geological history

Forms in hydrothermal veins, banded iron formations, and oxidation zones where iron-bearing fluids precipitate hematite. Deposits range from Precambrian formations to younger hydrothermal systems.

Uses & applications

Used as an iron ore, pigment, polishing powder, and ornamental mineral; attractive specular specimens are collected but are generally not used as gemstones.

Geological facts

The glitter comes from reflective hematite plates rather than true metallic flakes. Hematite is weakly magnetic or nonmagnetic, while associated magnetite may produce a stronger response.

Field identification & locations

Common localities include Brazil, Morocco, China, the United States, and Switzerland. Confirm with a reddish-brown streak and unusually heavy feel; the specimen appears consistent with a rough, silver-gray specular hematite piece.
