Physical properties
Hardness of 7 on the Mohs scale, milky white to translucent color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Forms primarily from hydrothermal veins and cooling magma chambers in igneous, metamorphic, and sedimentary environments globally.
Uses & applications
Used in glassmaking, abrasives, electronics oscillators, and as ornamental or decorative stone.
Geological facts
Milky quartz is the most common variety of crystalline quartz found on Earth, often appearing white due to microscopic fluid inclusions trapped during formation.
Field identification & locations
Easily identified by its high hardness (scratches glass), lack of cleavage, and characteristic cloudy white appearance. Found worldwide.
