Kyanite
Kyanite might be small but it sure does pack a powerful punch. The gemstone, very hard
and brittle, is most commonly found in the United States, Switzerland, Italy, Brazil, Austria,
India and Tanzania. The stone is most likely to be blue, streaked with black, green, purple,
or white, but there have been other varieties found in shades of yellow, pink, grey, white, and
orange.
