Physical properties

Hardness: 7 on Mohs scale; Color: White to translucent; Luster: Vitreous to greasy; Crystal system: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture); Specific gravity: 2.65

Formation & geological history

Formed through the crystallization of silica-rich hydrothermal solutions in veins or during the cooling of igneous magmas. Milky quartz gets its appearance from tiny fluid inclusions trapped during crystal growth.

Uses & applications

Used as an abrasive, in glass manufacturing, as a decorative stone in landscaping, and occasionally in jewelry as cabochons or beads. Also significant for spiritual/collector purposes.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Milky quartz is specifically distinct due to the 'frozen' gas and liquid bubbles that scatter light within the crystal structure.

Field identification & locations

Can be identified by its ability to scratch glass and lack of cleavage. Look for it in high-grade metamorphic regions or as veins within granite and other igneous rocks.
