Physical properties

Hardness of 7 on the Mohs scale, waxy to vitreous luster, conchoidal fracture, and typically translucent orange or peach coloration due to mineral inclusions.

Formation & geological history

Formed through the hydrothermal precipitation of silica-rich solutions in cavities or fractures of host rocks over millions of years.

Uses & applications

Commonly used in tumbled form for jewelry, decorative items, meditation, and crystal healing collections.

Geological facts

Quartz is one of the most abundant minerals on Earth and exhibits piezoelectric properties, generating an electrical charge under mechanical stress.

Field identification & locations

Easily identified by its lack of cleavage, high hardness, and smooth tumbled finish. Found worldwide in riverbeds and gem shops.
