Physical properties
Hardness of 7 on the Mohs scale, white to translucent color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity of 2.65.
Formation & geological history
Formed from hydrothermal solutions rich in silica cooling and precipitating within veins, cavities, and pegmatites across various geological eras.
Uses & applications
Widely used in gemstone carving, lapidary arts, metaphysical collections, and as an industrial source of high-purity silicon.
Geological facts
Milky quartz is the most common variety of crystalline quartz found globally, often appearing white due to microscopic fluid and gas inclusions trapped during growth.
Field identification & locations
Identified easily by its lack of cleavage, high hardness that scratches glass, and distinct milky-white coloration. Found worldwide, particularly in hydrothermal veins and pegmatites.
