Physical properties
Hardness of 7 on the Mohs scale, golden-brown to red-brown color, silky luster, hexagonal crystal system, and chatoyant optical effect.
Formation & geological history
Formed via pseudomorphous replacement of crocidolite fibers by silica, typically within ancient metamorphic rock formations.
Uses & applications
Widely used in jewelry, cabochons, ornamental carvings, and holistic healing practices.
Geological facts
The distinct chatoyancy or cat-eye effect is caused by the parallel arrangement of quartz crystals over altered amphibole fibers.
Field identification & locations
Identified by its signature golden stripes and silky light reflection; primarily sourced from South Africa and Western Australia.
