Physical properties

Hardness: 7 on Mohs scale; Color: Pale pink to rose red; Luster: Vitreous to greasy; Crystal Structure: Trigonal (often occurs as massive chunks); Cleavage: None (conchoidal fracture); Specific Gravity: 2.65.

Formation & geological history

Formed in high-temperature silica-rich magmatic environments, particularly pegmatites. The pink color is attributed to microscopic inclusions of manganese, titanium, or iron, though recent studies suggest fibrous dumortierite inclusions.

Uses & applications

Used extensively in jewelry (beads, cabochons), ornamental carvings, decorative objects, and is a popular specimen for rock collectors and metaphysical use.

Geological facts

Unlike other varieties of quartz, rose quartz rarely forms large, well-defined crystals. Most specimens found are 'massive,' meaning they are huge chunks without distinct crystal faces.

Field identification & locations

Identify in the field by its distinct pink translucent color, waxy luster, and its ability to scratch glass. It is commonly found in Brazil, Madagascar, South Africa, and the United States (South Dakota).
