Physical properties
Hardness of 7 on the Mohs scale, white to clear color with metallic flecks, vitreous luster, conchoidal fracture, and hexagonal crystal structure.
Formation & geological history
Formed through hydrothermal precipitation, where mineral-rich hot fluids crystallize within fractures of host rock over millions of years.
Uses & applications
Used for mineral specimen collecting, lapidary arts, and occasionally as an industrial source of high-purity silica.
Geological facts
Quartz veins are the primary geological structures that host economically significant deposits of gold and other precious metals.
Field identification & locations
Easily identified by its high hardness, vitreous luster, and association with dark host rock or metallic sulfide minerals.
