Physical properties

Hardness: 6.5-7 on Mohs scale; Color: Mint green with a matte/frosted finish; Luster: Vitreous (when polished) or matte (when blasted); Crystal structure: Trigonal (hexagonal); Cleavage: None

Formation & geological history

Formed in metamorphic rocks and magmatic environments. The green color comes from inclusions of green fuchsite mica within the quartz matrix. Most commercial aventurine is from India and Brazil.

Uses & applications

Used primarily in jewelry as beads and cabochons, for ornamental carvings, and in alternative healing practices.

Geological facts

Aventurine is known for the 'aventurescence' effect, which is a glittering or shimmering look caused by platy mineral inclusions. These specific beads have been frosted or sandblasted to create a soft, sea-glass like texture.

Field identification & locations

Identify by its characteristic green color and lack of transparency. In the field, look for its hardness (it should scratch glass) and its association with metamorphic terrains. These beads are uniform size, indicating industrial production.
