Quartz, silicon dioxide (SiO₂)

AI-generated identification · may be incorrect

Typically white to translucent with a vitreous luster; Mohs hardness 7, no cleavage, conchoidal fracture, and hexagonal crystal structure. The image is blurred, but the pale, cloudy appearance is consistent with milky quartz.

Physical properties

Formation & geological history

Forms in hydrothermal veins, pegmatites, and igneous or metamorphic rocks when silica-rich fluids crystallize; specimens may range from Precambrian to recent geological settings.

Uses & applications

Common quartz is used in glass, ceramics, abrasives, electronics, and engineered stone; attractive pieces are used as inexpensive decorative or lapidary material.

Geological facts

Milky color results from microscopic fluid inclusions, fractures, or defects that scatter light. Quartz is one of Earth’s most abundant and chemically durable minerals.

Field identification & locations

Identify it by its glassy luster, hardness sufficient to scratch ordinary glass, lack of cleavage, and irregular conchoidal fracture; common worldwide, especially in quartz veins and granitic terrains.
