Physical properties

Hardness of 7 on the Mohs scale, color ranges from milky white to translucent, vitreous to greasy luster, trigonal crystal system, conchoidal fracture, specific gravity of 2.65.

Formation & geological history

Formed in a wide variety of geological environments, frequently in hydrothermal veins, pegmatites, and as a primary component of igneous, metamorphic, and sedimentary rocks.

Uses & applications

Used in electronics, oscillators, glassmaking, abrasive materials, gemstone carving, and metaphysical practices.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust, surpassed only by feldspar. Its piezoelectric properties make it extremely valuable in electronic timekeeping.

Field identification & locations

Can be identified by its characteristic conchoidal fracture, high hardness (scratches glass easily), and lack of cleavage. Found globally in almost all geological terrains.
