Physical properties
Hardness of 7 on the Mohs scale, vitreous luster, conchoidal fracture, and hexagonal crystal system. Color ranges from colorless to white, gray, or various other hues.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of magma or precipitation from hydrothermal solutions over geological timescales.
Uses & applications
Widely used in electronics, glassmaking, precision instruments, and gemstone jewelry.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, making it essential for clocks and watches.
Field identification & locations
Easily identified by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture. Found worldwide in nearly all geological settings.
