Physical properties

Formation & geological history

Forms primarily in metamorphic rocks like phyllites and schists, or in hydrothermal veins. The color is typically caused by inclusions of mica or hematite. Age varies based on host rock location.

Uses & applications

Commonly used for lapidary work, jewelry making (beads, cabochons), decorative carvings, and in metaphysical practices as a 'stone of prosperity'.

Geological facts

Aventurine gets its name from the Italian word 'a ventura', meaning 'by chance', originally referring to accidental discovery of aventurine glass in the 18th century. Most aventurine is green, making yellow varieties more distinct for collectors.

Field identification & locations

Identify by its characteristic internal 'shimmer' or inclusions when rotated under light, and its ability to scratch glass. Commonly found in India, Brazil, and Russia. Look for a greasy to waxy feel if tumbled.
