Physical properties
Hardness of 7 on Mohs scale, white to milky color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through crystallization from silica-rich hydrothermal solutions or magmas over geological timescales.
Uses & applications
Used in glassmaking, electronics, abrasives, decorative objects, and lapidary work.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its high hardness (scratches glass) and lack of cleavage; commonly found worldwide in riverbeds, beaches, and quartz veins.
