  • Hematite Wikipedia

    Hematite, also spelled as haematite, is the mineral form of iron(III) oxide (Fe2O3), one of several iron oxides. It is the oldest known iron oxide mineral that has ever formed on earth, and is widespread in rocks and soils. Hematite crystallizes in the rhombohedral lattice system, and it has the same crystal structure as ilmenite and corundum.

  • Hematite Gemstone Information GemSelect

    Hematite is a gemstone form of iron oxide. It is the principal ore of iron and one of the few gemstones that exhibits a metallic luster. Like most other gemstones with a metallic luster, hematite is remarkably dense and possesses an extremely high refractive index. In fact, its specific gravity and refractive index is much higher than that of corundum, zircon and even diamond.
