Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to translucent soft rose-pink; Luster: Vitreous to waxy; Crystal Structure: Trigonal (macro-crystalline, usually found in massive form); Cleavage: None, exhibits conchoidal fracture; Specific Gravity: 2.65

Formation & geological history

Formed primarily in pegmatites and hydrothermal veins during igneous activity where trace amounts of titanium, iron, or manganese were present, imparting the delicate pink color.

Uses & applications

Widely used as a decorative gemstone, carved ornaments, tumbled stones for lapidary, beads for jewelry, and as a popular metaphysical crystal for collector markets.

Geological facts

Unlike clear quartz crystals, rose quartz almost always occurs in massive formations and rarely develops well-defined crystal faces. Deeply saturated pink specimens are sometimes referred to as 'crystalline rose quartz' or 'pink quartz'.

Field identification & locations

Identify by its characteristic hazy, translucent pale pink shade, lack of cleavage, glass-like luster, and hardness that easily scratches glass. Commonly found in Brazil, Madagascar, South Africa, and the USA (South Dakota).
