Rose quartz triple AAA-quality tumbled stones from Madagascar.

Rose quartz (stone of love) is a variety of quartz. The color varies from dark pink to very light, translucent pink. Rose quartz, named after the pink color, is often cracked and usually somewhat cloudy. The color-causing substances are titanium and manganese. The color can fade; very small rutile needles can cause a six-rayed star in cabochon cutting. Rose quartz has been processed as a gemstone for a long time. The best rose quartz is mined in Madagascar. Cat's eye effect rose quartz is found in Sri Lanka. It is also found in Kenya, Mozambique, and Namibia. In Brazil, there are numerous deposits, and rose quartz was first discovered in Minas Gerais in 1959. Some rose quartzes from Brazil exhibit chatoyancy or asterism. In the United States, rose quartz is found in the states of Maine, California, South Dakota, and Colorado. Asterism occurs in rose quartz from New York and Georgia. Russia, Kazakhstan, India, and Japan also supply rose quartz. Only rarely is rose quartz faceted in sizes larger than 20 carats. In the American Museum of Natural History, there is a 625-carat rose quartz sphere that exhibits asterism.
