Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. Typically colorless or white, but can be tinted various colors by impurities.
Formation & geological history
Forms in wide varieties of geological environments, including igneous, metamorphic, and sedimentary rocks, often crystallizing from hydrothermal solutions.
Uses & applications
Used extensively in electronics, glassmaking, abrasives, gemstones, and construction materials.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties, making it vital for precise timekeeping in watches.
Field identification & locations
Identified easily by its lack of cleavage, high hardness capable of scratching glass, and distinct conchoidal fracture. Found globally in almost all rock types.
