Physical properties
Hardness: 7 Mohs; Color: Colorless to white; Luster: Vitreous; Crystal Structure: Trigonal/Hexagonal; Cleavage: None; Specific Gravity: 2.65
Formation & geological history
Formed in igneous, metamorphic, and sedimentary environments as silica-rich fluids cool or precipitate. Found globally in pegmatites and hydrothermal veins.
Uses & applications
Jewelry, meditation, spiritual practices, glass making, and precision electronics due to piezoelectric properties.
Geological facts
Quartz is one of the most abundant minerals on Earth. Its name is derived from the German word 'Quarz', which means 'hard'.
Field identification & locations
Identify by its hardness (scratches glass), lack of cleavage, and transparency. Common in jewelry shops and rock collections.
