Tiger's Eye

Physical Properties

Hardness: 6.5-7.0 (Mohs); Color: Golden to reddish-brown; Luster: Silky; Crystal Structure: Hexagonal (trigonal); Cleavage: None; Specific Gravity: 2.64-2.71. It exhibits chatoyancy.

Formation & Geological History

Formed through a process of pseudomorphosis where blue asbestos fibers (crocidolite) are replaced by silica. This usually happens in metamorphic environments with hydrothermal activity.

Uses & Applications

Primarily used as a gemstone in jewelry (rings, pendants), decorative carvings, and as a popular specimen for crystal healing and metaphysical collections.

Geological Facts

The unique chatoyancy or 'cat's-eye' effect is produced by parallel fibers of crocidolite that have been fossilized by quartz. It is traditionally considered a stone of protection and good luck.

Field Identification & Locations

Identified by its characteristic silky luster and golden bands that seem to shift when the stone is tilted. It is most commonly found in South Africa, Western Australia, India, and Myanmar.
