Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed in a wide variety of geological environments, including hydrothermal veins, pegmatites, and as a primary component of igneous, metamorphic, and sedimentary rocks.
Uses & applications
Used in electronics, glassware, abrasive materials, gemstone carving, and decorative objects.
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 electrical charge under mechanical stress.
Field identification & locations
Easily identified by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture. Found worldwide.
