Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, hexagonal crystal system, conchoidal fracture with no true cleavage, and specific gravity around 2.65.
Formation & geological history
Formed through crystallization in igneous, metamorphic, and sedimentary environments, often rounded into pebbles by water transport in rivers or beaches.
Uses & applications
Used in glassmaking, electronics, abrasives, landscaping, and lapidary arts for decorative stones.
Geological facts
Quartz is one of the most abundant and durable minerals in Earth's continental crust, highly resistant to both chemical and mechanical weathering.
Field identification & locations
Identified easily by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture. Found worldwide in nearly all geological settings.
