Physical properties
Hardness: 7 Mohs; Color: Pale green to forest green; Luster: Vitreous to waxy; Crystal structure: Hexagonal; Specific gravity: 2.64-2.69; Translucency: Translucent to opaque with a characteristic shimmering glisten known as aventurescence.
Formation & geological history
Formed in metamorphic environments where quartz, mica, and other minerals recrystallize under high heat and pressure, typically found in magmatic deposits and regional metamorphic belts.
Uses & applications
Widely used in jewelry (beads, cabochons), home decor, tumbled stones for collecting, and as an ornamental stone in figurines and carvings.
Geological facts
The shimmering effect is caused by tiny inclusions of green chrome-rich mica called fuchsite; without these inclusions, it would simply be green quartz.
Field identification & locations
Identify by its 'shimmer' or sparkly inclusions under light; commonly found in India, Brazil, and Russia. For collectors, look for uniform green color and distinct aventurescence.
