Physical properties
Hardness of 7 on the Mohs scale, golden-brown to yellow-brown color, silky luster, hexagonal crystal system, and a distinct chatoyant optical effect.
Formation & geological history
Formed as quartz pseudo-morphs after crocidolite asbestos fibers, typically in metamorphic environments through silica-rich solutions altering iron-rich blue asbestos.
Uses & applications
Widely used for cabochons, beads, ornamental carvings, and popular as a semi-precious gemstone in jewelry.
Geological facts
The characteristic chatoyancy is caused by parallel intergrown quartz crystals and altered amphibole fibers that reflect light dynamically.
Field identification & locations
Easily identified by its distinctive golden silky stripes and chatoyant sheen when rotated; commonly sourced from South Africa and Western Australia.
