Physical properties
Hardness: 7 on Mohs scale; Color: Colorless to pale pink; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich magma or precipitation from hydrothermal veins. It is one of the most abundant minerals in the Earth's crust.
Uses & applications
Used in glassmaking, abrasives, electronic oscillators (due to piezoelectricity), and extensively in jewelry and gemstone collecting.
Geological facts
Quartz is piezoelectric, meaning it generates an electric charge when mechanical stress is applied. It is also the main constituent of most sand.
Field identification & locations
Identify by its hardness (scratches glass), lack of cleavage, and glassy appearance. Found globally in almost all geological settings, particularly in mountain ranges and riverbeds.
