Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the cooling and crystallization of silica-rich hydrothermal solutions or magma in various geological environments.
Uses & applications
Used in glassmaking, electronics, abrasives, gemstones, and ornamental carvings.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, meaning it generates an electric charge under mechanical stress.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture. Commonly found worldwide in pegmatites, hydrothermal veins, and sedimentary rocks.
