Physical properties

Formation & geological history

Formed in metamorphic rocks and pegmatites through the crystallization of silica-rich solutions where chromium-rich mica (fuchsite) is present. Most deposits range from the Precambrian to more recent geological eras.

Uses & applications

Extensively used for lapidary work including beads, figurines, jewelry, cabochons, and as a popular stone for chakra healing and crystal collecting. Historically used for tools before metalworking.

Geological facts

The name 'Aventurine' comes from the Italian 'a ventura', meaning 'by chance', originally referring to the accidental discovery of goldstone glass in the 18th century, which looks similar.

Field identification & locations

Identify by its green color and the subtle shimmer/sparkles (aventurescence) when rotated under light. Commonly found in India, Brazil, and Russia. It can be distinguished from jade by its hardness and grainy quartz texture.
