Physical properties
Hardness of 7 on the Mohs scale, white to translucent color, vitreous luster, hexagonal crystal system, conchoidal fracture.
Formation & geological history
Forms primarily from hydrothermal solutions and cooling magma in igneous, metamorphic, and sedimentary environments globally.
Uses & applications
Used in glassmaking, abrasives, electronics, and decorative lapidary work.
Geological facts
It is the most common variety of crystalline quartz, colored white by microscopic fluid inclusions trapped during formation.
Field identification & locations
Identified easily by its high hardness (scratches glass), lack of cleavage, and characteristic milky white appearance; found worldwide.
