Physical properties
Hardness of 7 on the Mohs scale, white to milky color, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.
Formation & geological history
Formed in hydrothermal veins and pegmatites through the precipitation of silica-rich fluids under high pressure and temperature.
Uses & applications
Widely used in decorative items, lapidary carvings, metaphysical practices, and gemstone collections.
Geological facts
Milky quartz is the most common variety of crystalline quartz, its white color caused by microscopic fluid inclusions trapped during crystal growth.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and smooth tumbled shape; commonly found worldwide.
