Hematite

Hematite is the iron oxide Fe₂O₃ and one of Earth’s principal iron ores. It occurs in platy, botryoidal, earthy or metallic forms. It is generally much less magnetic than magnetite; strongly magnetic “hematine” products in the market should not automatically be treated as natural hematite.

Hematite’s secret is the difference between surface and trace: crystals may look steel-grey or black, yet the streak is blood red. Its name is linked with the Greek word for blood. Ground hematite has long been a major component of red ochre, leaving marks on bodies and cave surfaces since prehistory.

In spiritual use, meaning is a layer distinct from mineral properties but still open to cultural study. Spiritual use treats hematite as a symbol of weight, body awareness, resolve and “grounding.” Its density and metallic appearance directly support that language, while the red streak suggests a trace of life within something outwardly cool.
