Physical properties

Hardness: 7 on Mohs scale; Color: Pink to rosy; Luster: Vitreous to dull in raw form; Crystal Structure: Hexagonal (trigonal); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65

Formation & geological history

Commonly forms in igneous pegmatites or hydrothermal veins. The pink color is often attributed to trace amounts of titanium, iron, or manganese, or microscopic inclusions of other minerals.

Uses & applications

Used primarily as decorative stone, in lapidary work for jewelry, and as a popular specimen for crystal collectors.

Geological facts

While rose quartz is famous for forming in large masses, individual crystals of pink quartz are exceptionally rare. Most pink quartz found in nature is 'massive' rather than 'crystalline'.

Field identification & locations

Identify by its hardness (will scratch glass), lacks cleavage, and its distinctive translucent pink hue. Often found in gravel beds or near granite outcroppings.
