Hematite is an opaque mineral with a metallic lustre. The name hematite stems from an ancient Greek word ‘haima’ meaning blood. Although, hematite is a dark grey silver colour with a reflective metallic surface, it leaves a rich red colour when rubbed against sandpaper. It also transforms into a red powder when ground down from which its name derives. Powdered hematite was mixed with water and used as face paint by native Americans for ritual ceremonies.
