Physical properties
Hardness of 7 on the Mohs scale, typically white or colorless, vitreous luster, hexagonal crystal system, conchoidal fracture.
Formation & geological history
Forms in a wide range of geological environments, including igneous, metamorphic, and sedimentary rocks, through hydrothermal processes and crystallization from silica-rich melts or solutions.
Uses & applications
Used extensively in electronics, glassmaking, abrasives, and as a semi-precious gemstone in jewelry and ornamentation.
Geological facts
Quartz is one of the most abundant and ubiquitous minerals in the Earth's continental crust. Its piezoelectric properties make it essential for frequency control in electronic devices.
Field identification & locations
Identified by its high hardness (scratches glass), conchoidal fracture, and lack of cleavage. Found worldwide in almost every geological setting.
