Physical properties

Formation & geological history

Forms in metamorphic environments, particularly in quartz veins and pegmatites where chromium-rich mica (fuchsite) is present, leading to its distinct green color.

Uses & applications

Used primarily in jewelry, ornamental carvings, tumbled stones, and for metaphysical and crystal healing practices.

Geological facts

The shimmering effect, known as aventurescence, is caused by tiny flat-faced inclusions of other minerals reflecting light. The name comes from the Italian 'avventura', meaning 'by chance'.

Field identification & locations

Can be identified by its characteristic green color combined with a sparkling metallic sheen when turned in the light. Commonly sourced from India, Brazil, Russia, and the USA.
