Physical properties
Hardness of 7 on the Mohs scale, typically white to clear color with vitreous luster, hexagonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed in hydrothermal veins and pegmatites through the cooling and precipitation of silica-rich solutions over millions of years.
Uses & applications
Used in electronics, watchmaking, optical instruments, and as a popular specimen for mineral collectors and jewelry.
Geological facts
Quartz is one of the most abundant minerals in 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 hardness (scratches glass) and hexagonal crystal habit. Found worldwide in virtually all geological environments.
