Physical properties
Hardness of 7 on the Mohs scale, translucent to opaque, pale to dark green color, and vitreous to greasy luster with a trigonal crystal system.
Formation & geological history
Forms in hydrothermal veins and pegmatites through the precipitation of silica-rich solutions containing chromium-rich mica flakes.
Uses & applications
Widely used in tumbled decorative stones, jewelry, carving, and as a popular meditation and crystal healing specimen.
Geological facts
The distinctive green shimmer or glitter effect, known as aventurescence, is caused by tiny reflective flakes of the mineral fuchsite trapped inside.
Field identification & locations
Easily identified by its characteristic green color combined with the telltale sparkling metallic sheen and a conchoidal fracture.
