Physical properties

Hardness: 7 on Mohs scale; Color: Yellow to golden orange; Luster: Vitreous to waxy; Crystal structure: Hexagonal/Trigonal; Cleavage: None; Specific gravity: 2.64–2.69

Formation & geological history

Formed in metamorphic environments where quartz-rich sediments or magmatic deposits are subjected to high pressure and heat, incorporating mica inclusions during crystallization.

Uses & applications

Primarily used for decorative purposes, jewelry (cabochons and beads), and in metaphysical or holistic healing practices.

Geological facts

The characteristic 'aventurescence' (shimmer) in aventurine is caused by tiny mineral inclusions. In yellow aventurine, these are often muscovite or pyrite, which give it its distinct golden glow.

Field identification & locations

Identify by its waxy luster and internal shimmer. It is commonly found in India, Brazil, and Russia. Collectors look for uniform color and strong 'sparkle' within the stone.
