Physical properties
Hardness: 7 (Mohs), Color: Clear/White crystals on gray matrix, Luster: Vitreous/Glassy, Crystal System: Hexagonal, Cleavage: None/Conchoidal fracture
Formation & geological history
Formed in hydrothermal veins or geodes where silica-rich fluids precipitate into cavities within volcanic or sedimentary host rocks. Most specimens range from late Paleozoic to Tertiary ages.
Uses & applications
Primarily used for mineral collecting, lapidary work, jewelry (pendants/rings), and metaphysical purposes. Industrial quartz is used in glass and electronics.
Geological facts
Druzzy refers to a coating of fine crystals on a rock surface. Quartz is one of the most abundant minerals on Earth and the primary constituent of most sand.
Field identification & locations
Identified by the sparkle of countless small crystal faces and its ability to scratch glass. Commonly found worldwide, especially in areas with historical volcanic activity or geothermal springs.
