Physical properties

Mohs hardness of 7, white to pale yellow or greenish color with a sparkling or sugary luster, trigonal crystal system with microcrystalline quartz crust, conchoidal fracture, specific gravity of 2.65.

Formation & geological history

Formed when silica-laden water condenses on a rock's surface, cooling rapidly and causing minute quartz crystals to precipitate and grow over millions of years.

Uses & applications

Commonly used in jewelry making, wire-wrapping, ornamental display pieces, and spiritual or metaphysical practices.

Geological facts

Druzy refers to the fine coating of miniature crystal points on a rock fracture surface, resembling tiny sugar grains sparkling in the light.

Field identification & locations

Easily identified by its distinct sugary texture and glittering appearance under light; found in cavities of various host rocks worldwide.
