Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, conchoidal fracture, and hexagonal crystal system.
Formation & geological history
Formed through crystallization in igneous, metamorphic, and sedimentary environments over millions of years, frequently weathered and rounded by water transport.
Uses & applications
Commonly used in glassmaking, electronics, abrasives, decorative landscaping, and lapidary arts.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Easily identified by its high hardness, lack of cleavage, and resistance to chemical weathering; found globally in rivers, beaches, and soil.
