Physical properties
Hardness: 7 on the Mohs scale, Color: White to milky white, Luster: Vitreous to greasy, Crystal Structure: Trigonal, Cleavage: None (exhibits conchoidal fracture), Specific Gravity: 2.65
Formation & geological history
Forms in a wide range of geological environments, commonly in hydrothermal veins, pegmatites, and as a primary component of igneous, metamorphic, and sedimentary rocks.
Uses & applications
Used in electronics, glassmaking, abrasive materials, gemstone carving, and mineral collections.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electric charge under mechanical stress.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and vitreous luster. Commonly found worldwide in beaches, riverbeds, and mountainous regions.
