Physical properties

Hardness of 7 on the Mohs scale, distinct translucent green color with a shimmering effect called aventurescence, and a vitreous to greasy luster.

Forms in metamorphic environments and hydrothermal veins through the deposition of silica-rich solutions containing chromium-rich mica.

Widely used in polished tumbled stones, jewelry, carvings, and as a popular crystal for decorative purposes.

The shimmering appearance is caused by tiny flat plate-like inclusions of green fuchsite mica suspended within the quartz matrix.

Identified by its characteristic green sparkle under light and quartz hardness, commonly found in India, Brazil, and Russia.
