Physical properties

Hardness: 6.5-7 Mohs; Color: Golden-brown, blue-black; Luster: Silky; Structure: Hexagonal (Trigonal); Cleavage: None; Specific Gravity: 2.64-2.71

Formation & geological history

Formed when silica-rich fluids replace fibrous crocidolite (asbestos) in iron-rich metamorphic environments. This specimen shows transition between golden and blue (Hawk's Eye) varieties.

Uses & applications

Metaphysical collecting, jewelry cabochons, ornamental carvings, and decorative stones.

Geological facts

Tiger's Eye is a 'pseudomorph,' meaning its internal structure consists of one mineral (Quartz) that has replaced another (Crocidolite) while retaining the original fibrous shape which creates 'chatoyancy.'

Field identification & locations

Identified by its distinctive silky luster and light-reflecting chatoyant bands. Commonly found in South Africa and Australia. Collectors look for high-contrast banding and 'flash.'
