Physical properties
Hardness of 7 on the Mohs scale, pale to dark green color, vitreous to greasy luster, hexagonal crystal system, distinct sparkly or glistening effect (aventurescence) due to mineral inclusions, specific gravity of 2.65.
Formation & geological history
Forms in metamorphic environments, particularly in quartz veins and pegmatites, often associated with tectonic pressures and hydrothermal activity.
Uses & applications
Widely used in tumbling, carving, making ornamental objects, and jewelry, as well as valued by collectors and practitioners of crystal healing.
Geological facts
The sparkling effect in green aventurine is known as aventurescence, which is caused by tiny reflective flakes of green mica (fuchsite) trapped inside the quartz matrix.
Field identification & locations
Easily identified by its translucent to opaque light green color and signature metallic shimmer. Found globally, with notable deposits in India, Brazil, Russia, and the United States.
