Rainbow Hematite (Titanium Coated)

Physical Properties

Hardness: 5.5-6.5 on Mohs scale; Color: Multi-colored iridescence (purple, blue, green, gold); Luster: Metallic; Crystal Structure: Trigonal; Cleavage: None; Specific Gravity: 5.26

Formation & Geological History

Natural hematite forms in hydrothermal veins or as a result of magmatic differentiation. The iridescence in this specific specimen is usually created via a man-made process called Magnetron Sputtering, where the stone is coated with a thin layer of titanium or gold.

Uses & Applications

Primarily used for decorative jewelry, beadwork, holistic healing practices, and as a pocket stone for collectors.

Geological Facts

Natural iridescent hematite does exist (sometimes called Turgite), but most perfectly spherical or tumbled 'rainbow' specimens found in gift shops are enhanced. Hematite is the most important ore of iron.

Field Identification & Locations

Identify by its weight (it is very dense for its size) and a reddish-brown streak if rubbed on unglazed porcelain. It is commonly found in Brazil, Australia, and the Lake Superior region of North America.
