Physical properties

Hardness: 7 on Mohs scale; Color: Colorless to white; Luster: Vitreous (glassy); Crystal Structure: Hexagonal/Trigonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Formed from silica-rich hydrothermal solutions or as a cooling product of igneous pegmatites. It can form in various temperatures and pressures across all geological ages.

Uses & applications

Used in electronics for its piezoelectric properties, glass manufacturing, abrasives, jewelry, and widely collected for ornamental or metaphysical purposes.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Pure quartz is known as rock crystal, used historically to make lenses and spheres.

Field identification & locations

Identify by its hexagonal prism shape and horizontal striations on crystal faces. Common in many environments; look for it in granite outcrops or vein deposits.
