Physical properties
Hardness of 7 on the Mohs scale, white or milky color, vitreous to greasy luster, hexagonal crystal system, conchoidal fracture with no true cleavage.
Formation & geological history
Forms abundantly in igneous, metamorphic, and sedimentary environments through the crystallization of silica-rich hydrothermal solutions or cooling magma.
Uses & applications
Widely used in jewelry, decorative carvings, electronics, and glass manufacturing.
Geological facts
Milky quartz gets its cloudy appearance from microscopic fluid inclusions trapped during crystal growth.
Field identification & locations
Easily identified by its high hardness (scratches glass) and lack of cleavage; found globally in nearly all geological settings.
