Physical properties

Hardness: 7 on Mohs scale. Color: Translucent yellowish-tan to pale champagne. Luster: Vitreous to sparkling (druzy surface). Crystal system: Trigonal/Hexagonal. Cleavage: None (conchoidal fracture).

Formation & geological history

Formed via hydrothermal activity where silica-rich fluids deposit microscopic quartz crystals inside rock cavities, geodes, or fractures over thousands to millions of years.

Uses & applications

Used extensively in lapidary arts, metaphysical jewelry, decorative specimens, and as a gemstone. Also used industrially in electronics and optics when pure.

Geological facts

Druzy quartz features a coating of fine crystals crystallizing on top of a mineral matrix. Quartz is the second most abundant mineral in Earth's continental crust.

Field identification & locations

Identified by its sparkling micro-crystalline surface texture and scratch resistance to steel (hardness 7). Commonly found worldwide in pegmatites, hydrothermal veins, and geodes.
