Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. Color is typically white or transparent but can vary widely due to impurities.
Formation & geological history
Forms in a wide range of geological environments, including igneous, metamorphic, and sedimentary rocks, often crystallizing from silica-rich hydrothermal veins.
Uses & applications
Widely used in electronics, glassmaking, abrasives, and as a semi-precious gemstone in jewelry and ornamentation.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, meaning it generates electric charge under mechanical stress.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage. Found worldwide in nearly every geological setting.
