Physical properties
Hardness of 7 on Mohs scale, typically colorless or white but can be various colors, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through crystallization from silica-rich melts or solutions over geological timescales.
Uses & applications
Used widely in electronics, glassmaking, abrasives, and as a semi-precious gemstone in jewelry and lapidary arts.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits piezoelectric properties, making it essential in timekeeping devices.
Field identification & locations
Identified by its high hardness, lack of cleavage, and distinct conchoidal fracture; found globally in pegmatites, hydrothermal veins, and sandstones.
