Physical properties
Hardness of 7 on the Mohs scale, transparent to translucent color, vitreous luster, hexagonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from hydrothermal veins and cooling magma chambers in igneous, metamorphic, and sedimentary environments worldwide.
Uses & applications
Used extensively in electronics, oscillators, glassmaking, gemstone carving, and decorative mineral collections.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits piezoelectric properties, generating an electric charge under mechanical stress.
Field identification & locations
Identified by its distinct hexagonal prismatic crystal habit, lack of cleavage, and high hardness capable of scratching glass; commonly found in pegmatites and quartz veins.
