Physical properties
Mohs hardness of 7, white to milky color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from cooling magma in igneous pegmatites or via hydrothermal vein deposition over millions of years.
Uses & applications
Widely used in jewelry, gemstone carving, decorative items, and metaphysical healing practices.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust and exhibits strong piezoelectric properties.
Field identification & locations
Identified by its high hardness (scratches glass) and lack of cleavage; found globally in almost all geological environments.
