Physical properties
Hardness of 7 on the Mohs scale, white to translucent color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture.
Formation & geological history
Forms primarily from hydrothermal veins, pegmatites, and igneous or metamorphic processes across a wide geological timeframe.
Uses & applications
Used in glassmaking, electronics, abrasives, and as ornamental or lapidary specimens.
Geological facts
Milky quartz is the most common variety of quartz found on Earth, often appearing white due to microscopic fluid inclusions trapped during formation.
Field identification & locations
Identified easily by its high hardness, lack of cleavage, and distinct white coloration; found worldwide in virtually all geological environments.
