Physical properties
Hardness 6.5-7 on Mohs scale, colors range from yellow-brown to golden-brown, silky luster, trigonal crystal structure, specific gravity 2.58-2.64.
Formation & geological history
Formed by the alteration of crocidolite, a type of asbestos, which is replaced by quartz over time. Often found in metamorphic rocks.
Uses & applications
Used primarily in jewelry, ornamental carvings, and as a collector's stone.
Geological facts
Known for its chatoyancy, a 'cat's eye' effect caused by the parallel alignment of crocidolite fibers.
Field identification & locations
Recognized by its golden to red-brown color and chatoyant luster. Commonly found in South Africa, Australia, and parts of the US.
