Physical properties
Hardness of 7 on the Mohs scale, white or translucent color, vitreous luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the weathering and water-tumbles erosion of larger quartz veins or igneous and metamorphic rocks over millions of years.
Uses & applications
Used in decorative landscaping, polished into ornamental stones and jewelry, and utilized in glassmaking and electronics.
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
Easily identified by its high hardness which scratches glass and its lack of reaction to acid. Commonly found in riverbeds and beaches worldwide.
