Physical properties
Hardness of 7 on Mohs scale, transparent to translucent white or clear color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed via crystallization in igneous, metamorphic, and sedimentary environments, often rounded by aqueous transport and weathering in riverbeds or beaches.
Uses & applications
Used in glassmaking, electronics, abrasives, gemstones, and as decorative landscape or aquarium gravel.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and resistance to chemical weathering. Found worldwide.
