Physical properties
Hardness: 7 on the Mohs scale. Color: Light to dark green, often with a shimmering effect (aventurescence). Luster: Vitreous to greasy. Crystal structure: Trigonal. Cleavage: None. Specific gravity: 2.65.
Formation & geological history
Forms in metamorphic environments, specifically in quartz veins and pegmatites, often as a result of regional metamorphism. Geological age varies widely depending on the host rock formation.
Uses & applications
Widely used in jewelry, carvings, ornamental items, and crystal healing practices.
Geological facts
The shimmering effect, known as aventurescence, is caused by tiny reflective flakes of green mica (fuchsite) trapped inside the quartz matrix.
Field identification & locations
Identified by its distinctive green color combined with a metallic shimmer under light and a hardness that easily scratches glass. Commonly found in India, Brazil, Russia, and Austria.
