Physical properties

Hardness: 7 on Mohs scale; Color: Milky white to translucent; Luster: Vitreous/glassy; Crystal Structure: Trigonal/Hexagonal; Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Formed from cooling silica-rich hydrothermal solutions or magma. The milky appearance is caused by tiny fluid inclusions of gas or liquid trapped during crystal growth. Found in various geological environments from igneous to metamorphic rocks.

Uses & applications

Used for decorative purposes, metaphysical collecting, gemstones, and industrial silica. This specific item is a hand-carved ornamental figurine.

Geological facts

Quartz is the second most abundant mineral in Earth's continental crust. Milky quartz specifically gets its 'cloudy' appearance from microscopic bubbles of water or carbon dioxide trapped inside.

Field identification & locations

Identify in the field by its hardness (cannot be scratched by steel), glassy luster, and lack of cleavage. It is found globally, with significant deposits in Brazil, the USA (Arkansas), and Madagascar.
