Physical properties
Hardness of 7 on the Mohs scale, white to translucent color, vitreous to greasy luster, trigonal crystal system, and conchoidal fracture with no true cleavage.
Formation & geological history
Formed predominantly in hydrothermal veins, pegmatites, and igneous or metamorphic rocks through the cooling and precipitation of silica-rich fluids.
Uses & applications
Used in glassmaking, abrasives, electronics, and as an ornamental gemstone or collector mineral.
Geological facts
It is the most common variety of crystalline quartz found on Earth, often appearing milky white due to microscopic fluid inclusions trapped during growth.
Field identification & locations
Easily identified in the field by its high hardness (scratches glass), white color, and distinct conchoidal fracture; found worldwide in virtually all geological environments.
