Physical properties
Hardness of 7 on the Mohs scale, pale to dark green color, vitreous to greasy luster, trigonal crystal system, and a specific gravity of 2.65.
Formation & geological history
Forms hydrothermally within metamorphic quartzites and schist environments through the inclusion of chrome-rich mica flakes during crystallization.
Uses & applications
Widely used in tumbled stones, carved sculptures, gemstone jewelry, and decorative objects.
Geological facts
The characteristic shimmering green sparkle, known as aventurescence, is caused by tiny reflective flakes of green mica called fuchsite trapped inside the quartz matrix.
Field identification & locations
Easily identified by its distinct green color combined with a glittering metallic sheen and high quartz hardness. Major deposits are found in India, Brazil, and Russia.
