Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, white to grayish color, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through hydrothermal precipitation, where silica-rich fluids crystallized within fractures of pre-existing rock over millions of years.
Uses & applications
Used in industrial applications, glassmaking, electronics, and collected as geological specimens.
Geological facts
Quartz veins are the primary geological structures that host native gold and other hydrothermal ore deposits worldwide.
Field identification & locations
Easily identified in the field by its high hardness, glassy luster, and resistance to weathering standing out against darker host rock.
