Physical properties
Hardness of 7 on the Mohs scale, typically exhibits a vitreous to greasy luster, conchoidal fracture, and lacks true cleavage. Color ranges from pink, purplish, to earthy brownish-red depending on trace inclusions.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments. Often crystallizes from silica-rich hydrothermal veins and pegmatites, or precipitates in sedimentary settings.
Uses & applications
Used in lapidary arts, ornamental carvings, crystal healing, and as gemstone specimens for collectors.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and is well-known for its piezoelectric properties, which are utilized in electronic oscillators.
Field identification & locations
Easily identified by its hardness (scratches glass), lack of cleavage, and conchoidal fracture. Found worldwide in nearly every geological environment.
