Its name is derived from the Greek word for blood, into its red colour. Many of the various forms of hematite have separate names. The steel-gray crystals and coarse-grained varieties have a brilliant metallic lustre and are known as specular iron ore; thin scaly types are called micaceous hematite. Much hematite occurs in a soft, fine-grained, earthy form called red ochre or ruddle. Intermediate between these types are compact varieties, often with a reniform surface (kidney ore) or a fibrous structure (pencil ore). Red ochre is used as a paint pigment; a purified form, rouge, is used to polishplate glass. It is easy to confuse the mineral hematite with the man-made material that goes by the name “magnetic hematite.” In certain forms, both share a very similar silvery appearance. In addition, both are often confused with the mineral magnetite. Hematite and magnetite are both iron oxide minerals, but magnetic hematite, though containing iron, is a manufactured ceramic material that is marketed and sold for its silvery appearance and magnetic properties. True hematite is not magnetic Many people wonder, Is hematite magnetic? The answer is, no, hematite isn’t particularly magnetic naturally. While it does contain iron oxide, the magnetic field is incredibly weak
