Hematite

Hematite is an iron oxide mineral (Fe₂O₃) whose name comes from the Greek haima, meaning 'blood,' because it produces a blood-red streak when scratched across unglazed porcelain, despite having a metallic silver-black to steel-grey surface. This dual nature — appearing one colour while being another — is itself a philosophical curiosity. Hematite is so iron-rich that it is mined as an ore; the extraordinary banded iron formations of Western Australia and Brazil are among the world's most significant industrial iron deposits, geological monuments to an ancient cataclysm when the first photosynthetic life oxygenated the Earth's atmosphere.

Hematite has been used as a pigment and protective material since prehistoric times — the ochre used in cave paintings is iron oxide, the same compound as hematite. Native Americans used red ochre in ceremonies and battle paint. Egyptian priests ground hematite into powder for use in healing. The stone was called 'bloodstone' in the ancient world (a different application than modern bloodstone/heliotrope) and was used to stop bleeding and reduce inflammation in medical traditions across Europe and Asia.

In contemporary crystal work, hematite is the pre-eminent grounding stone — its high iron content is believed to connect the holder powerfully to the Earth's own electromagnetic field, anchoring scattered or floating energy. It is used to overcome feelings of dissociation, anxiety, or overwhelm; to build physical strength and resilience; and to create clear energetic boundaries between oneself and draining external influences.
