Description
A pink quartz used as a gemstone and ornamental stone. Rose quartz has been mined or gathered since the early iron age (1200-500 BCE). It is found in the Ural Mountains, Czech Republic, Germany (Bavaria), Scotland, Ireland, Sweden, Italy, India, Madagascar, Namibia, Brazil (Minas Gerais), and the U.S.(South Dakota, California, Montana, South Dakota, Maine). Rose quartz ranges in color from a pale pink to a deep rose red. Transparent rose quartz is used as a gemstone while translucent varieties have been used for vases, ornaments and architectural elements. Some rose quartz may have needlelike inclusions of rutile that induce a star-shaped chatoyancy.
