Physical properties
Hardness of 7 on the Mohs scale, golden-yellow to brown color with chatoyant (silky) luster, and a hexagonal crystal system.
Formation & geological history
Formed as a pseudomorph of quartz replacing the original mineral crocidolite through silica deposition and iron oxidation.
Uses & applications
Widely used in ornamental carvings, cabochons for jewelry, and as a popular collector mineral.
Geological facts
The distinctive chatoyancy (cat's-eye effect) is caused by the parallel inclusion of altered amphibole fibers within the quartz matrix.
Field identification & locations
Identified by its characteristic golden stripes and silky light reflection; primarily sourced from South Africa and Western Australia.
