Hematite

Hematite (Fe₂O₃), likely a polished specular hematite palm stone

AI-generated identification · may be incorrect

Hardness 5–6.5 Mohs; metallic steel-gray to black color, very high metallic luster, opaque, and commonly weakly magnetic or nonmagnetic. It has a trigonal crystal structure but is often massive or polished, with a diagnostic red-brown streak.

Physical properties

Formation & geological history

Forms by oxidation of iron-rich minerals, in hydrothermal veins, sedimentary iron formations, and metamorphic rocks; deposits range from Precambrian to modern. This specimen appears human-polished rather than naturally crystal-faced.

Uses & applications

Used as an iron ore and pigment; polished pieces are sold as ornamental stones, meditation stones, and inexpensive collectibles. It is not typically a jewelry gemstone of high value.

Geological facts

Despite its shiny metallic appearance, hematite’s streak is red to reddish brown, unlike magnetite’s black streak. Some commercial “magnetic hematite” items are actually synthetic ferrite or hematite–magnetite mixtures.

Field identification & locations

Test an inconspicuous area for a red-brown streak on unglazed ceramic; check magnetism and compare density (about 5.3 g/cm³). Common sources include Brazil, Australia, China, the United States, and Canada.
