Physical properties

Hardness: 7 (Mohs); Color: Green with a shimmering effect; Luster: Vitreous to waxy; Crystal Structure: Hexagonal (trigonal); Cleavage: None; Specific Gravity: 2.63 - 2.65

Formation & geological history

Formed in metamorphic environments where quartz-rich sediment is subjected to heat and pressure, allowing mica inclusions to align and create the characteristic 'aventurescence'.

Uses & applications

Commonly used for lapidary work, jewelry, decorative carvings, and as a popular stone for chakra healing and metaphysical collections.

Geological facts

The shimmering effect is called aventurescence, which is caused by tiny platelike inclusions of green mica called fuchsite. Its name is derived from the Italian 'a ventura', meaning 'by chance'.

Field identification & locations

Identify by its characteristic green color and internal glitter-like sparkles. Found primarily in India, Brazil, and Russia. It is often mistaken for nephrite jade but is harder and has a granular texture.
