Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Formed through the cooling and crystallization of silica-rich hydrothermal solutions within cracks and veins of the Earth's crust.
Uses & applications
Widely used in glassmaking, electronics, abrasive materials, and ornamental jewelry or metaphysical collections.
Geological facts
Quartz is one of the most abundant minerals on Earth and exhibits piezoelectric properties, meaning it generates an electrical charge under mechanical stress.
Field identification & locations
Identified easily by its high hardness which scratches glass, lack of cleavage, and distinct conchoidal fracture; found globally in nearly all geological environments.
