Physical properties
Hardness of 7 on Mohs scale, vitreous luster, translucent white to grey color, and conchoidal fracture without cleavage.
Formation & geological history
Formed through the weathering and water-transport rounding of hydrothermal veins or quartz-rich igneous and metamorphic rocks.
Uses & applications
Used in decorative landscaping, glass manufacturing, abrasives, and as a common specimen for rock collectors.
Geological facts
Quartz is one of the most abundant and durable minerals on Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Identified easily by its inability to be scratched by a steel knife and its smooth, water-worn shape found frequently in riverbeds and beaches.
