Physical properties
Hardness: 7 on Mohs scale; Color: Pale mint green; Luster: Vitreous to waxy; Crystal structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture); Specific gravity: 2.65
Formation & geological history
Formed in hydrothermal veins or through metamorphism. Green coloring is typically caused by inclusions of fuchsite mica or chlorite (Aventurine) or natural/artificial irradiation/heating (Prasiolite).
Uses & applications
Used extensively in jewelry, ornamental carvings, lapidary arts, and as a popular healing stone in metaphysical communities.
Geological facts
Aventurine is often called the 'Stone of Opportunity' and is often confused with jade at first glance. The shimmering effect seen in some specimens is called aventurescence.
Field identification & locations
Identified by its hardness (scratches glass), lack of cleavage, and translucent pale green body. Commonly found in Brazil, India, and Russia. Look for a granular texture or tiny mica flakes inside the stone.
