Physical properties

Formation & geological history

Formed in hydrothermal veins and pegmatites through precipitation of silica-rich fluids in cavities and fractures under heat and pressure over millions of years.

Uses & applications

Used in electronics (piezoelectric applications), glassmaking, abrasives, gemstones, decorative specimens, and mineral collections.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. The white, cloudy appearance of milky quartz is caused by millions of tiny gas or liquid bubbles trapped during crystal growth.

Field identification & locations

Identified in the field by its hardness (scratches glass easily), lack of cleavage, milky translucency, and hexagonal prismatic crystal terminations. Widely distributed worldwide in granitic pegmatites and quartz veins.
