Blue Topaz

Blue Topaz is the hardest of the silicate minerals. While pure Topaz is colorless, minor changes of elements within the stone result in a variety of other colors, such as blue, pale green, red, yellow and pink.
Topaz is found primarily in Brazil, Nigeria, Sri Lanka, Mexico, Pakistan, China, and the United States.
Blue Topaz was considered by ancient civilizations to have cooling properties. Not only was it believed to cool boiling water when thrown into the pot, but to calm hot tempers as well! This gemstone was credited with many other healing powers, among them the ability to cure insanity, asthma, weak vision and insomnia. The Blue Topaz was even thought to have magical properties in its ability to make its wearer invisible in a threatening situation.
