Physical properties
Hardness of 7 on the Mohs scale, typically pale pink to white in color, vitreous (glassy) luster, trigonal crystal system, lacks distinct cleavage, specific gravity of 2.65.
Formation & geological history
Formed in igneous, metamorphic, and sedimentary environments. Often crystallizes from silica-rich hydrothermal solutions at varying geological ages.
Uses & applications
Used in jewelry, ornamental carvings, glassmaking, electronics (oscillator crystals), and crystal healing/collecting.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust. It exhibits piezoelectric properties, meaning it can generate an electrical charge in response to mechanical stress.
Field identification & locations
Easily identified by its hardness (scratches glass), conchoidal fracture, and lack of cleavage. Found worldwide in nearly every geological environment.
