Physical properties

Hardness: 7 on Mohs scale; Color: Colorless to milky white; Luster: Vitreous (glassy); Crystal Structure: Hexagonal (trigonal); Cleavage: None, exhibits conchoidal fracture; Specific Gravity: 2.65

Formation & geological history

Formed from silica-rich hydrothermal solutions or the cooling of magma in pegmatites. It can be found in igneous, metamorphic, and sedimentary environments worldwide.

Uses & applications

Used in electronics (oscillators), optics, glassmaking, abrasives, jewelry, and as a popular specimen for collectors.

Geological facts

Quartz is one of the most abundant minerals in Earth's crust. It is piezoelectric, meaning it generates an electric charge when mechanical pressure is applied.

Field identification & locations

Identify by its hexagonal crystal habit, lack of cleavage, and ability to scratch glass. It is commonly found in mountain ranges and riverbeds globally.
