Physical properties

Hardness: 7 (Mohs scale), Color: Colorless to white, Luster: Vitreous (glassy), Crystal structure: Hexagonal (trigonal), Cleavage: None (conchoidal fracture), SG: 2.65

Formation & geological history

Formed through the cooling of silica-rich magma or from hydrothermal solutions in veins. They are found in igneous, metamorphic, and sedimentary rocks across various geological ages.

Uses & applications

Used in electronics (oscillators), glass manufacturing, abrasives, jewelry (gemstones), and as decorative interior specimens or for metaphysical collecting.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Pure quartz is traditionally called rock crystal or clear quartz.

Field identification & locations

Identify in the field by its hexagonal crystal habit with horizontal striations on the faces and its ability to scratch glass. Commonly found in pegmatites and mountain ranges worldwide.
