Physical properties
Hardness: 7 (Mohs scale), Color: Pinkish-brown to white, Luster: Vitreous to greasy, Crystal Structure: Trigonal, Cleavage: None/Conchoidal fracture, Specific Gravity: 2.65
Formation & geological history
Formed in hydrothermal veins and pegmatites through the cooling of silica-rich magma or from supercritical fluids in the Earth's crust over millions of years.
Uses & applications
Used as a gemstone, for ornamental carvings, as a source of silica for glass manufacturing, and in electronic oscillators and high-frequency equipment.
Geological facts
Quartz is the second most abundant mineral in the Earth's continental crust. Iron staining can give white quartz a reddish or brownish surface appearance, mimicking rose quartz.
Field identification & locations
Check for hexagonal crystal hints and hardness (should scratch glass but not be scratched by a steel file). Commonly found in mountainous regions or inside riverbeds.
