Although rose quartz is usually too cloudy to be used as a cut gemstone, a few exceptional pieces are found with enough clarity and color to make fine gems. Most gemmy rose quartz is used as cabochons where the clarity is not as important as the color. Rose quartz is also a very attractive ornamental stone and is carved into spheres, pyramids, obelisks, figurines and ornate statues.
Rose quartz is found in Madagascar, India, Germany, and several localities in the USA. Much rose quartz was extracted from a famous site near Custer, South Dakota, but now, most of the worlds supply of good quality rose quartz comes from Brazil.
Brazil is also the only current source of true well-formed crystals of rose quartz. Rose quartz was once believed to be only massive, found primarily in the cores of pegmatites. This lack of crystals is somewhat of a curiosity because quartz crystallizes into well-formed crystals in all its other macroscopic varieties. So amazing are the rose quartz crystals that the first ones discovered were dismissed as fakes by mineralogists from around the world.
Rose quartz is only one of several quartz varieties. Other varieties that form macroscopic (large enough to see) crystals are as follows:
