- Hematite: the principal form of iron ore; consists of ferric oxide in crystalline form; occurs in a red earthy form
- Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum. Hematite and ilmenite form a complete solid solution at temperatures above 950u00A0u00B0C (1,740u00A0u00B0F).
- Alternative spelling of hematite
- Is a form of iron oxide and is used in jewellery in its hardest and most compact form. Most forms of haematite are black in colour.
- Iron ore; red or metallic dark grey
