Physical properties
Hardness of 7 on the Mohs scale, color ranges from peach to pink, vitreous to greasy 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, commonly in igneous pegmatites, hydrothermal veins, and as detrital grains in sedimentary rocks due to its high resistance to weathering.
Uses & applications
Used in lapidary arts, jewelry, decorative tumbled stones, and for metaphysical purposes.
Geological facts
Quartz is one of the most abundant minerals in Earth's continental crust. Peach or pink coloration is often due to microscopic inclusions of dumortierite, iron oxides, or irradiation.
Field identification & locations
Easily identified by its high hardness (scratches glass), lack of cleavage, and conchoidal fracture. Found worldwide in stream beds, gravel deposits, and mineral shops.
