Physical properties
Hardness of 7 on the Mohs scale. Color is light to dark green with a shimmering effect known as aventurescence. Luster is vitreous to greasy. Crystal system is trigonal. Conchoidal fracture with no true cleavage. Specific gravity is 2.65.
Formation & geological history
Formed in metamorphic and igneous environments, often as hydrothermal veins or in pegmatites and quartzites where chromium-rich mica (fuchsite) inclusions develop during crystallization.
Uses & applications
Commonly used in crystal healing, ornamental carvings, polished stones, beads, and affordable jewelry.
Geological facts
The shimmering effect, or aventurescence, is caused by tiny reflective flakes of green mica (fuchsite) trapped inside the quartz matrix during formation.
Field identification & locations
Easily identified by its translucent green body combined with a metallic or glittering sheen under light. Found worldwide, with significant deposits in India, Brazil, Russia, and the United States.
