Physical properties
Hardness of 7 on the Mohs scale, yellowish to golden color due to iron oxide inclusions, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed in hydrothermal veins, pegmatites, and sedimentary environments through the crystallization of silica-rich solutions under varying temperatures and pressures over millions of years.
Uses & applications
Used in jewelry, decorative carvings, metaphysical practices, and mineral collections.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust. Variations in color are typically caused by trace impurities like iron or natural irradiation.
Field identification & locations
Can be identified by its conchoidal fracture, lack of cleavage, and scratching glass (hardness 7). Found worldwide in various geological settings.
