Physical properties

Formation & geological history

Forms in metamorphic environments, particularly in quartz-rich schists and gneisses, as well as in igneous pegmatites and hydrothermal veins where silica-rich fluids precipitate quartz containing platy mineral inclusions like fuchsite.

Uses & applications

Commonly used in tumbled stones, carved sculptures, decorative items, and jewelry such as rings, necklaces, and beads.

Geological facts

The shimmering effect, known as aventurescence, is caused by tiny reflective flakes of chrome-bearing micas like fuchsite trapped inside the quartz matrix during crystallization.

Field identification & locations

Identified by its distinct green color combined with a metallic glittering sheen under light, a conchoidal fracture, and a hardness that easily scratches glass. Major deposits are found in India, Brazil, Russia, and Austria.
