Physical properties
Hardness of 7 on the Mohs scale, vitreous to greasy luster, white to translucent with darker matrix inclusions, trigonal 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 fluids over geological time scales.
Uses & applications
Used in mineral specimen collecting, lapidary arts, and decorative objects.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust, known for its piezoelectric properties and durability.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture. Found worldwide in various geological settings.
