Physical properties

Hardness of 7 on the Mohs scale, transparent to translucent with white, gray, and dark metallic patches, vitreous luster, conchoidal fracture, and no true cleavage.

Formation & geological history

Formed in hydrothermal veins where hot, mineral-rich fluids cooled and precipitated silica and other metallic minerals within cracks and fissures of host rock over millions of years.

Uses & applications

Used in mineral collecting, lapidary arts, and ornamental display pieces.

Geological facts

Quartz is one of the most abundant minerals on Earth's continental crust and frequently hosts valuable ore minerals such as pyrite, chalcopyrite, or galena within its crystal matrix.

Field identification & locations

Can be identified by its high hardness (scratches glass), glassy luster, and conchoidal fracture. Often found in quartz veins traversing metamorphic or igneous terrains.
