Physical properties
Hardness of 7 on Mohs scale, typically white or colorless, vitreous luster, hexagonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through crystallization from silica-rich melts or hydrothermal solutions over millions of years.
Uses & applications
Widely used in electronics, glassmaking, abrasive powders, and decorative gemstones or metaphysical collections.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture; found globally in veins, pegmatites, and sands.
