Physical properties

Hardness: 5.5-6.5 on Mohs scale; Color: Black to steel-gray with a metallic luster; Crystal structure: Hexagonal (natural) or ceramic composite; Highly magnetic; Density: approx. 5.3 g/cm3.

Formation & geological history

While natural Hematite is formed in sedimentary, igneous, or metamorphic environments (often in banded iron formations), these specific 'stones' are man-made magnetic ceramics created by powdering hematite and magnetite and bonding them with ferrite under high heat.

Uses & applications

Used primarily for magnetic therapy jewelry, worry stones, executive desk toys (magnets), and mass-market souvenirs/education kits.

Geological facts

Natural hematite is usually only weakly magnetic. The strong magnetism in these tumbled stones is a result of industrial processing. Hematite is the most important ore of iron.

Field identification & locations

Identify by its 'gunmetal' metallic sheen and strong magnetic attraction. In the field, natural hematite is best identified by its reddish-brown streak on a porcelain plate, regardless of the outer color.
