Additional Info
Kyanite got its name from the Greek word "kyanos", which simply means "blue". Gems with intense sapphire blue color are the most valuable. One peculiarity about Kyanite is that depending on crystallographic direction, it has two different hardnesses (7 and 4.5).

Where to buy?
For Kyanite check what Amazon has to offer. You'll usually find quite a selection from many different vendors. Worth a check. For other high quality gemstones (Rubies, Saphhires, Emeralds) and especially Diamonds, I highly recommend JamesAllen.
