Physical properties
Hardness of 7 on the Mohs scale, white to clear color, vitreous luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the precipitation from silica-rich hydrothermal solutions or crystallization in igneous and metamorphic environments, highly resistant to weathering.
Uses & applications
Used in glassmaking, electronics, abrasives, and as decorative landscape gravel or tumbling stones.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage; found globally in beaches, rivers, and soils.
