Physical properties
Hardness: 7 on Mohs scale. Color: Pale to dark green due to fuchsite mica inclusions. Luster: Vitreous to greasy, often with a shimmering effect known as aventurescence. Crystal structure: Trigonal. Cleavage: None.
Formation & geological history
Formed in metamorphic environments, specifically regional or contact metamorphism of quartz-rich rocks where chromium-rich muscovite (fuchsite) crystallizes within the silica matrix.
Uses & applications
Used widely in carving, ornamental objects, tumbled stones, jewelry, and metaphysical practices.
Geological facts
The shimmering effect, or aventurescence, is caused by tiny reflective flakes of mineral inclusions trapped inside the quartz during its growth.
Field identification & locations
Identified by its characteristic green color, glassy luster, and shimmering metallic specks when rotated under a light source. Found globally including in India, Brazil, Russia, and the United States.
