Physical properties

Formation & geological history

Formed in igneous pegmatites or hydrothermal veins under high pressure and temperature. The pink color is often attributed to microscopic inclusions of dumortierite or manganese.

Uses & applications

Commonly used for lapidary work, decorative ornamental carvings, crystal healing collections, and as an ore of silica.

Geological facts

Rose quartz is unique because it rarely forms distinct crystals with faces; instead, it usually grows in massive, irregular lumps. The dark material attached is likely a mica-schist matrix common in many pegmatitic environments.

Field identification & locations

Identify by its characteristic pink hue and its ability to scratch glass (hardness 7). It is commonly found in Brazil, Madagascar, and the Black Hills of South Dakota. Collectors should look for depth of color and clarity.
