Physical properties
Hardness of 7 on the Mohs scale, translucent to opaque green color with a shimmering or glittering metallic luster (aventurescence) caused by platy mineral inclusions, and a trigonal crystal system.
Formation & geological history
Forms within metamorphic rocks, particularly quartz veins and pegmatites, through the hydrothermal precipitation of silica-rich solutions containing chromium-bearing minerals over millions of years.
Uses & applications
Widely used for ornamental carvings, polished worry stones, beads, and jewelry making due to its attractive sparkle and durability.
Geological facts
The glittering effect is known as aventurescence, a term derived from the Italian word 'avventura' meaning by chance, which describes the accidental discovery of synthetic glass with a similar appearance.
