Physical properties

Hardness: 7 on Mohs scale; Color: Colorless/Transparent; Luster: Vitreous; Crystal Structure: Hexagonal (trigonal); Cleavage: None/Conchoidal fracture; Specific Gravity: 2.65

Formation & geological history

Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich magma or from hydrothermal veins. It is one of the most abundant minerals in the Earth's crust.

Uses & applications

Used in electronics for its piezoelectric properties, glass manufacturing, abrasives, and widely in jewelry and carvings.

Geological facts

Quartz is piezoelectric, meaning it generates an electric charge in response to applied mechanical stress. It is known as the 'Universal Crystal' in many cultures.

Field identification & locations

Identify by its hardness (scratches glass), lack of cleavage, and transparent appearance. Commonly found worldwide in mountain ranges and riverbeds. Look for hexagonal prism habits in the field.
