Physical properties

Hardness: 7 Mohs; Color: Clear to light smoky/brownish; Luster: Vitreous/glassy; Structure: Hexagonal; Cleavage: None/Conchoidal fracture; Specific gravity: 2.65

Formation & geological history

Formed by the precipitation of mineral-rich water in rock cavities, often in volcanic geodes or sedimentary veins, typically during the Cenozoic era or older.

Uses & applications

Used primarily for metaphysical collecting, jewelry making, and home decor specimens.

Geological facts

The word 'drusy' refers to a coating of fine crystals on a rock surface; it creates a sugar-like glittering effect that is highly prized in modern artisan jewelry.

Field identification & locations

Identify by the presence of small, sparkling pyramidal crystal terminations covering a host rock; look for it in volcanic regions or within limestone cavities.
