Physical properties

Hardness: 7 on Mohs scale; Color: Milky white to translucent; Luster: Vitreous to greasy; Crystal structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture).

Formation & geological history

Forms through the crystallization of silica-rich hydrothermal fluids in veins or as a primary constituent in igneous rocks like granite. The milky appearance is caused by tiny fluid or gas inclusions trapped during crystal growth.

Uses & applications

Used as an ornamental stone, a source of silica for glass and electronics, and frequently used in lapidary work for cabochons or decorative carvings.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Milky quartz is often referred to as 'Snow Quartz' in metaphysical circles.

Field identification & locations

Identified by its white color, inability to be scratched by steel, and lack of cleavage. It is found globally, particularly in areas with hydrothermal activity or metamorphic outcrops.
