Overview of Hematite
About
Hematite is an iron oxide mineral known for its metallic sheen and earthy red undertones. While typically found in a steel-grey to black colour with a metallic lustre when polished, its powdered form appears reddish-brown, giving it its name, derived from the Greek word "haima" meaning blood. Hematite is often used in jewellery, carvings, and as a grounding stone in crystal healing. It is heavy due to its iron content, making it distinctively dense compared to other gemstones.
Hematite History and Folklore
Birthstones & Anniversaries

Similar Materials
Magnetite: Sometimes confused with hematite due to its metallic appearance, magnetite is magnetic, unlike true hematite.
Specularite: A variety of hematite with a sparkling appearance due to mica-like inclusions.
Goethite: A mineral that can sometimes appear similar to hematite but has different physical properties and tends to have a more yellow-brown tone.
Treatments
Hematite is typically untreated, though it is often polished to enhance its natural metallic lustre. Some imitation hematite beads are created using magnetic materials or coated plastics.
Synthetics
There are no widely produced synthetic versions of hematite.
Imitations
Imitation hematite, also known as hematine, is usually made from magnetic materials or plastics coated to resemble hematite’s metallic appearance. True hematite is non-magnetic, so a simple test can often differentiate between the two.
