Physical properties
Mohs hardness of 7, colorless or transparent, vitreous luster, hexagonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Formed from cooling silica-rich hydrothermal solutions in igneous and metamorphic environments over millions of years.
Uses & applications
Widely used in electronics, jewelry, decorative items, and metaphysical healing practices.
Geological facts
Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its high hardness, glassy luster, and lack of cleavage; found globally in pegmatites, hydrothermal veins, and sedimentary rocks.
