A part of the Microcline class of the Feldspar group, this gemstone's name comes from the belief that it came from the Amazon River in South America. It is an iridescent stone that varies in color from pale green to blue green. Different shades of these colors can show up in the same stone, as Amazonite is not uniform in color. Amazonite is found in granite rocks and is mined throughout the world in places like Brazil, Madagascar, Namibia, Zimbabwe, Australia, Russia, and the U.S. Amazonite is usually set as a cabochon since it breaks easily if faceted. It is not produced synthetically. Amazonite is thought to improve skin, alleviate stress and exhaustion. Women were told to wear Amazonite to keep marriages happy.
