Physical properties

Hardness of 7 on the Mohs scale, transparent to translucent with a vitreous luster, trigonal crystal system, conchoidal fracture with no true cleavage, specific gravity around 2.65.

Formation & geological history

Formed in hydrothermal veins and pegmatites through the cooling and crystallization of silica-rich fluids under high pressure and temperature over millions of years.

Uses & applications

Commonly used in lapidary work, jewelry making, crystal healing, and mineral specimen collecting.

Geological facts

Quartz is one of the most abundant minerals in the Earth's continental crust and exhibits piezoelectric properties, meaning it can generate an electrical charge when mechanical stress is applied.

Field identification & locations

Easily identified by its high hardness (scratches glass) and conchoidal fracture. Found worldwide in nearly all geological environments, particularly in pegmatites and hydrothermal quartz veins.
