Physical properties

Hardness: 7 (Mohs scale), Color: Clear to milky white, Luster: Vitreous (glassy), Crystal structure: Hexagonal/Trigonal, Cleavage: None (conchoidal fracture), Specific gravity: 2.65

Formation & geological history

Formed from silica-rich hydrothermal fluids precipitating in rock cavities or fractures. It can occur in various geological ages and environments, particularly in igneous or metamorphic host rocks.

Uses & applications

Used primarily in jewelry (beads, pendants), mineral collecting, and metaphysical displays. Industrial quartz is used in glassmaking and electronics.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. 'Druze' or 'Drusy' refers to the tiny crystals that form on the surface of another mineral or rock.

Field identification & locations

Identify by its characteristic hexagonal crystal points and its ability to scratch glass but not be scratched by steel. Commonly found in areas with high volcanic or tectonic activity.
