Physical properties
Hardness of 7 on the Mohs scale, white to translucent color, vitreous luster, trigonal crystal system, and no cleavage.
Formation & geological history
Formed via hydrothermal precipitation or crystallization in igneous and metamorphic rocks, later weathered and rounded by water transport.
Uses & applications
Used in landscaping, decorative stone, glass manufacturing, and electronics.
Geological facts
Quartz is one of the most abundant and durable minerals on Earth's continental crust.
Field identification & locations
Identified by its high hardness (scratches glass) and conchoidal fracture, commonly found in stream beds and beaches.
