Physical properties

Hardness of 7 on the Mohs scale, colorless to white, vitreous luster, hexagonal crystal system, conchoidal fracture, specific gravity of 2.65.

Formation & geological history

Forms in hydrothermal veins, pegmatites, and as a primary component in igneous, metamorphic, and sedimentary rocks across various geological eras.

Uses & applications

Widely used in electronics, oscillator frequency control, glass manufacturing, abrasives, and decorative gemstone jewelry or crystal collecting.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust and exhibits strong piezoelectric properties, generating an electrical charge under mechanical stress.

Field identification & locations

Easily identified by its high hardness (scratches glass), lack of cleavage, and characteristic conchoidal fracture. Found worldwide.
