Physical properties
Hardness: 7 (Mohs scale), Color: Pale pinkish-orange to milky white, Luster: Vitreous (glassy) to greasy, Crystal: Hexagonal, Cleavage: None (conchoidal fracture), Specific Gravity: 2.65
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments. Typically crystallizes from cooling magma or hydrothermal veins. This specimen appears water-worn or tumbled.
Uses & applications
Used in manufacturing of glass, abrasives, electronics, and as a semi-precious gemstone in jewelry and metaphysical collecting.
Geological facts
Quartz is one of the most abundant minerals on Earth. Its piezoelectric properties make it vital for quartz watches and clocks.
Field identification & locations
Identify by its hardness (scratches glass), lack of cleavage, and conchoidal fracture. Found worldwide in riverbeds and mountainous regions.
