Physical properties
Hardness: 7 (Mohs scale), Color: White to translucent milky white, Luster: Vitreous (glassy), Crystal Structure: Hexagonal (trigonal), Cleavage: None/Conchoidal fracture, Specific Gravity: 2.65
Formation & geological history
Formed from silica-rich hydrothermal solutions or as a primary constituent in igneous rocks like granite. Found worldwide in nearly every geological environment.
Uses & applications
Used in ornamental carvings, jewelry, spiritual/metaphysical practices, and industrial glass-making. Highly valued by collectors for its purity and clarity.
Geological facts
Quartz is one of the most abundant minerals in Earth's crust. Milky quartz gets its cloudy appearance from minute fluid inclusions of gas or liquid trapped during crystal growth.
Field identification & locations
Identify by its hardness (it will easily scratch glass) and lack of cleavage planes. Look for a waxy or glassy luster and a white or clear streak.
