Physical properties
Hardness of 7 on the Mohs scale; green color due to chromium-rich fuchsite mica flakes; vitreous to greasy luster; hexagonal crystal system (microcrystalline quartz aggregate); specific gravity of 2.65.
Formation & geological history
Formed in metamorphic environments, specifically in quartz veins and pegmatites, where hydrothermal solutions deposit silica along with tiny flakes of mica or other minerals.
Uses & applications
Commonly used in jewelry, gemstone carvings, tumbled stones, and wire-wrapped pendants.
Geological facts
Aventurine displays a glistening effect known as aventurescence, caused by the reflective metallic inclusions within the quartz matrix.
Field identification & locations
Identified by its distinctive green color coupled with a shimmering or glittering appearance when turned in the light. Often found in India, Brazil, Russia, and the United States.
