Physical properties
Hardness of 7 on the Mohs scale, typically white or translucent pink, vitreous luster, hexagonal crystal system, and no cleavage.
Formation & geological history
Formed through hydrothermal veins and igneous pegmatites, later smoothed by natural water action or mechanical tumbling.
Uses & applications
Used widely in lapidary arts, jewelry making, ornamental decor, and mineral collections.
Geological facts
Quartz is the most abundant and varied mineral found in Earth's continental crust.
Field identification & locations
