Physical properties
Hardness of 7 on the Mohs scale, orange to pink color, vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Forms in a wide variety of geological environments, most commonly in igneous, metamorphic, and sedimentary rocks as well as hydrothermal veins.
Uses & applications
Used in electronics, oscillators, glassware, abrasives, gemstone carving, and mineral collections.
Geological facts
Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electric charge under mechanical stress.
Field identification & locations
Easily identifiable due to its high hardness (scratches glass) and lack of cleavage. Found globally in almost all rock types.
