Physical properties

Hardness: 6.5-7 Mohs; Color: Green with shimmering spots; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: None; Specific gravity: 2.64-2.69

Formation & geological history

Formed in metamorphic rocks and hydrothermal veins through the crystallization of silica-rich solutions. Its green color and aventurescence (metallic shimmer) are caused by inclusions of green chrome-mica (fuchsite).

Uses & applications

Commonly used for lapidary work, cabochons, beads, decorative carvings, and as a popular stone for chakra or metaphysical collections.

Geological facts

Aventurine is known for the optical phenomenon 'aventurescence,' which creates a glittering effect. While most common in green, it can also be found in blue, red, orange, and peach depending on the mineral inclusions.

Field identification & locations

Identify by its deep green color and the presence of tiny glittering mica inclusions when rotated under light. Commonly found in India, Brazil, and Russia. Collectors should look for even color and a strong shimmer.
