Physical properties

Formation & geological history

Quartz commonly grows from silica-rich hydrothermal fluids in rock cavities or fractures; such deposits formed across many geological ages.

Uses & applications

Collected as a decorative specimen and sometimes used in ornaments or lapidary work; quartz is also important in glassmaking and electronics.

Geological facts

Quartz is one of Earth’s most abundant minerals and occurs in many colors and forms.

Field identification & locations

Look for glassy sparkle, hardness sufficient to scratch ordinary glass, and lack of cleavage; common worldwide in veins and geodes. The specimen appears hand-sized, but locality and exact identification are unknown.
