Physical properties
Hardness of 7 on the Mohs scale, translucent to opaque, with a vitreous to greasy luster and a characteristic sparkly appearance known as aventurescence.
Formation & geological history
Formed through the regional metamorphism of quartz-rich sandstone, where chromium-rich mica (fuchsite) flakes become trapped during recrystallization.
Uses & applications
Widely used in ornamental carvings, polished cabochons, beads, and metaphysical crystal healing practices.
Geological facts
The shimmering effect is caused by tiny platelike mineral inclusions reflecting light. It is often confused with jade but can be distinguished by its quartz composition and distinct sparkle.
Field identification & locations
Found globally in India, Brazil, Russia, and the United States; easily identified in the field by its green color and glittering texture.
