Hematite: ("hei-daan") is a facinating stone. Black or dark gray, it has a deep luster that seems to glow from within. On the Mohs hardness scale hematite rates 5½ to 6½.
Ancient peoples sometimes used hematite crystals as mirrors; indeed, the Latin name for hematite, "specularite," means "mirror." The word hematite derives from the Greek word for "blood," because when the stone is cut, the coolant is colored red. In fact, hematite is often found with reddish bands of other meterials.
The stone is found in England, Germany, Scandinavia as well as Spain, Brazil and New Zealand.
Hematite has been used to decrease inflammation, drawing out heat from a feverish part of the body. It is said to dissolve negative energy and to work as a shield of armor for any person or thing
