Physical properties
Hardness of 7 on the Mohs scale, milky white color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in a wide variety of geological environments, most commonly in hydrothermal veins, pegmatites, and as a primary component of igneous, metamorphic, and sedimentary rocks.
Uses & applications
Used in glassmaking, electronics, oscillators, abrasives, gemstones, and ornamental carvings.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electric charge under mechanical stress.
Field identification & locations
Easily identified by its hardness (scratches glass), lack of cleavage, and conchoidal fracture. Found worldwide, commonly in river gravels and quartz veins.
