Physical properties

Hardness: 7 (Mohs scale); Color: Clear to milky white/light tan; Luster: Vitreous (glassy); Crystal Structure: Hexagonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Formed through hydrothermal processes where silica-rich fluids precipitate in rock cavities or veins. This specimen shows a druzy clusters of macro-crystals likely formed in a volcanic or sedimentary pocket.

Uses & applications

Used in gemstone production, decorative aquarium/home decor, and as a raw source of silicon for electronics; highly prized by mineral collectors.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. This specific 'druzy' formation refers to the coating of crystals onto a rock surface.

Field identification & locations

Identify by its ability to scratch glass and its distinct six-sided terminations. Found globally, especially in regions with igneous activity or sandstone formations.
