Physical properties
Hardness of 7 on the Mohs scale, green color with a shimmering metallic luster (aventurescence), trigonal crystal system, and conchoidal fracture.
Formation & geological history
Formed in metamorphic environments and hydrothermal veins through the precipitation of silica-rich solutions containing chromium-bearing mica.
Uses & applications
Widely used in tumbled stones, ornamental carvings, and low-cost jewelry.
Geological facts
The shimmering effect is caused by tiny flat inclusions of reflective minerals like fuchsite trapped inside the quartz matrix.
Field identification & locations
Easily identified by its distinct green sparkle when rotated under a light source; commonly sourced from India, Brazil, and Russia.
