Physical properties
Hardness of 7 on the Mohs scale, green color due to chromium-rich mica inclusions, translucent to opaque luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed through the hydrothermal alteration of quartz veins or in metamorphic environments, often found in quartz-rich quartzites and pegmatites.
Uses & applications
Used in ornamental carvings, tumbling, jewelry, and crystal healing.
Geological facts
The name comes from the Italian 'a ventura', meaning 'by chance', referring to the accidental discovery of a similar glass material in the 18th century.
Field identification & locations
Easily identified by its distinctive silvery-green metallic sheen (aventurescence) caused by mineral inclusions within the quartz matrix.
