Physical properties
Hardness of 7 on Mohs scale, white to milky color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Forms primarily from cooling magma in igneous pegmatites and hydrothermal veins, as well as through metamorphic and sedimentary processes across various geological eras.
Uses & applications
Used widely in glassmaking, electronics, abrasive materials, engineered stone countertops, and gemstone carving.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electric charge under mechanical stress.
Field identification & locations
Easily identified by its lack of cleavage, high hardness capable of scratching glass, and conchoidal fracture; found worldwide in almost every geological environment.
