Physical properties

Hardness: 7 Mohs; Color: Pale to golden yellow; Luster: Vitreous to waxy; Crystal Structure: Hexagonal/Trigonal; Cleavage: None/Conchoidal fracture; Specific Gravity: 2.64-2.69

Formation & geological history

Formed through metamorphic or igneous processes where silica-rich solutions cool and crystallize, with the presence of mica or iron-oxide inclusions creating the yellow hue.

Uses & applications

Used primarily in decorative arts, jewelry carving, metaphysical practices, and as collector gemstones.

Geological facts

Aventurine is known for its 'aventurescence,' a shimmering effect caused by plate-like mineral inclusions inside the quartz.

Field identification & locations

Identify by its hardness (will scratch glass) and characteristic grainy, shimmering internal appearance. Commonly sourced from Brazil, India, and Russia.
