Physical properties
Hardness: 7 on Mohs scale. Color: Green to yellowish-green. Luster: Vitreous to greasy. Crystal structure: Trigonal (microcrystalline quartz aggregate). Cleavage: None. Specific gravity: 2.65.
Formation & geological history
Formed in metamorphic environments, particularly through regional metamorphism of quartz-rich sandstone containing chromium-bearing micas (fuchsite) or other green minerals.
Uses & applications
Used in ornamental carvings, polished stones, beads, jewelry, and crystal healing.
Geological facts
The distinctive green shimmer or sparkle (aventurescence) is caused by tiny reflective flakes of fuchsite or other mineral inclusions trapped within the quartz matrix.
Field identification & locations
Easily identified by its translucent green color and characteristic glittery appearance under direct light. Commonly found in India, Brazil, Russia, and the United States.
