Physical properties
Hardness: 7 on Mohs scale. Color: Pale to deep green with a shimmering effect (aventurescence). Luster: Vitreous to waxy. Crystal Structure: Trigonal/Hexagonal. Cleavage: None.
Formation & geological history
Formed metamorphic conditions where silica-rich fluids deposit quartz containing tiny flakes of chromium-rich mica (fuchsite), which gives the green color and sparkly shimmer.
Uses & applications
Popular for lapidary work, cabochons, beads, carvings, decorative objects, and crystal healing collections.
Geological facts
The distinctive shimmering appearance is called 'aventurescence', caused by light reflecting off tiny mineral inclusions inside the quartz.
Field identification & locations
Identified by its medium green color, hardness, and shimmering sparkling specks under light. Major sources include India, Brazil, Russia, and South Africa.
