Physical properties
Hardness of 7 on the Mohs scale, white to milky color due to microscopic fluid inclusions, vitreous to greasy luster, hexagonal 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 electronics for oscillator crystals, glass manufacturing, abrasives, and gemstone or lapidary carvings.
Geological facts
Milky quartz is the most common variety of quartz found on Earth and owes its cloudy appearance to trapped gas or liquid bubbles during crystallization.
Field identification & locations
Easily identified in the field by its distinct white milky coloration, high hardness of 7, and lack of cleavage. Found worldwide.
