Physical properties
Hardness of 7 on the Mohs scale, white to clear color, vitreous luster, conchoidal fracture, and no cleavage with a specific gravity of 2.65.
Formation & geological history
Formed through crystallization in igneous, metamorphic, and sedimentary environments, often shaped into smooth pebbles by water transport and mechanical weathering.
Uses & applications
Used in glassmaking, electronics, abrasives, and as a decorative landscaping stone or polished pocket specimen.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties, meaning it generates an electric charge under mechanical stress.
Field identification & locations
Identified easily by its inability to be scratched by steel and its distinct conchoidal fracture; commonly found in riverbeds, beaches, and alluvial gravels worldwide.
