Physical properties
Hardness of 7 on the Mohs scale, yellowish-brown to golden color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed in hydrothermal veins and pegmatites through the precipitation of silica-rich fluids under high pressure and temperature.
Uses & applications
Used in jewelry, ornamental carvings, glassmaking, and electronic oscillators due to its piezoelectric properties.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and resists weathering exceptionally well.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture. Found worldwide in nearly all geological environments.
