Rose quartz
Pink variety of quartz
Rose quartz is a pink, translucent variety of quartz with a massive habit. Its color is due to microscopic inclusions of a fibrous silicate mineral related to dumortierite. Previously, the color was believed to be due to inclusions of rutile. Rose quartz is dichroic and may display asterism when cut into spheres or cabochons. It formed at very high temperatures of 400-700 °C (752-1,292 °F) in the quartz cores of pegmatites. Rose quartz is commonly used in lapidary for carvings and as a semiprecious gemstone.
Rose quartz is always anhedral and does not occur as well-formed crystals. However, there is a distinct variety of pink-colored quartz called euhedral rose quartz or pink quartz that occurs as well-formed crystals. This variety derives its color from the presence of aluminium and phosphorus color centers in the crystal structure activated by natural irradiation. Unlike massive rose quartz, pink quartz is photosensitive and subject to fading. Pink quartz crystals are transparent and formed as late-stage hydrothermal deposits within pegmatite pockets.
