Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from cooling magma in hydrothermal veins and pegmatites, as well as through metamorphic and sedimentary processes across various geological ages.
Uses & applications
Used in electronics, glassmaking, abrasives, decorative items, and jewelry.
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
Easily identified by its high hardness (scratches glass) and lack of cleavage; found worldwide in virtually all geological environments.
