Physical properties
Hardness of 7 on the Mohs scale, light to dark green color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in metamorphic environments, specifically in quartz veins and pegmatites, where hydrothermal solutions deposit silica containing platy inclusions of green minerals like fuchsite.
Uses & applications
Commonly used in tumbled stones, jewelry, carvings, and as a decorative ornamental stone. Popular in crystal healing and collecting.
Geological facts
The characteristic shimmer or glitter effect (aventurescence) in aventurine is caused by tiny reflective inclusions of other minerals, most commonly green fuchsite mica.
Field identification & locations
Easily identified by its translucent green color and subtle metallic glitter. Found worldwide, with major deposits in India, Brazil, Russia, and the United States.
