Physical properties
Hardness of 7 on the Mohs scale, distinct golden-brown to yellow-brown stripes, silky luster, and a microcrystalline quartz crystal structure.
Formation & geological history
Formed when quartz gradually replaces the original fibrous mineral crocidolite, preserving its fibrous structure through pseudomorphism.
Uses & applications
Widely used in jewelry, cabochons, ornamental carvings, and holistic healing collections.
Geological facts
It exhibits chatoyancy, an optical reflectance effect that creates a moving silky light band resembling a tiger's eye.
Field identification & locations
Easily identified by its distinctive golden stripes and silky sheen. Primarily sourced from South Africa and Australia.
