Physical properties

Hardness: 7 on the Mohs scale. Color: Colorless to white. Luster: Vitreous (glassy). Crystal structure: Trigonal/Hexagonal. Cleavage: None (conchoidal fracture). Specific gravity: 2.65.

Formation & geological history

Formed from silica-rich hydrothermal solutions or cooling magma in igneous rocks like granite. It is found in all types of geological environments and can be millions of years old.

Uses & applications

Used in electronics (oscillators), luxury glassmaking, jewelry (as a gemstone), abrasive manufacturing, and spiritual/metaphysical collecting.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. It is piezoelectric, meaning it generates an electric charge in response to applied mechanical stress.

Field identification & locations

Identify by its ability to scratch glass and lack of cleavage. Look for hexagonal crystal faces and conchoidal (curving) fractures. Very common in mountainous regions and riverbeds.
