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.
