Physical properties
Mohs hardness of 7; white to milky translucent color; vitreous to greasy luster; hexagonal crystal system; conchoidal fracture with no true cleavage.
Formation & geological history
Forms in igneous, metamorphic, and sedimentary environments through the cooling of silica-rich solutions or magma over millions of years.
Uses & applications
Used in jewelry, ornamental carvings, electronics, glassmaking, and metaphysical crystal healing practices.
Geological facts
Milky quartz gets its cloudy appearance from microscopic fluid inclusions trapped during crystal growth. It is one of the most abundant minerals on Earth's continental crust.
Field identification & locations
Identified by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture. Found worldwide in nearly every geological setting.
