Physical properties

Formation & geological history

Rose quartz forms mainly in granitic pegmatites and hydrothermal quartz veins, with its color commonly related to microscopic inclusions of minerals such as dumortierite. The specimen’s exact geological age and locality cannot be determined from the image.

Uses & applications

Used as an ornamental stone, beads, carvings, polished pebbles, and inexpensive jewelry; it has little industrial value compared with ordinary quartz.

Geological facts

Rose quartz is usually massive rather than well-crystallized; transparent pink quartz crystals are rarer and may be classified separately as pink quartz.

Field identification & locations

Identify it by its pink color, glassy/waxy surface, lack of obvious cleavage, and hardness sufficient to scratch glass. Common sources include Brazil, Madagascar, India, South Africa, and the United States.
