Physical properties
Hardness of 7 on the Mohs scale, milky white to clear color, vitreous to greasy luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed primarily in hydrothermal veins, pegmatites, and igneous or metamorphic rocks through the crystallization of silica-rich fluids.
Uses & applications
Used in glass manufacturing, electronics, abrasives, gemstones, and decorative ornamental items.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage; globally distributed in nearly all geological environments.
