Physical properties

Hardness: 6.5-7.0 (Mohs scale); Color: Golden yellow to brown with chatoyant bands; Luster: Silky; Crystal Structure: Trigonal (fibrous aggregate); Cleavage: None; Specific Gravity: 2.64-2.71

Formation & geological history

Formed through the pseudomorphism of crocidolite (asbestos) by quartz. It typically forms in metamorphic environments where quartz layers replace the fibrous mineral while maintaining its structure.

Uses & applications

Predominantly used as a gemstone in jewelry (rings, beads, cabochons), carvings, and as a popular specimen for crystal healing and metaphysical collections.

Geological facts

The unique 'cat's eye' effect is called chatoyancy. Historically, Tiger's Eye was once more valuable than gold until large deposits were discovered in South Africa in the 19th century.

Field identification & locations

Identify by its distinct chatoyant bands that seem to shift when the stone is tilted. It is most commonly found in the Northern Cape Province of South Africa, Australia, and Namibia.
