Kyanite is an interesting gem that was discovered during the nineteenth century. The most highly prized kyanite is the vibrant blue or blue-green hue. It is also found in shades of gray, yellow, white and a colorless variety that is considered quite rare.
It was once believed that a kyanite suspended from a human hair could follow the earth's magnetic force. Early travellers sometimes used it as a compass when exploring unknown territories.
The fan like clusters or blades that are formed by kyanite make it an ideal stone for restoring energy balance. It is a very effective energy conduit that can balance most systems of the body. It can quickly create stillness and tranquility, making it an excellent stone for meditation. 
One of the most interesting of crystals is Kyanite, which consists of multiple layers of very thin, flat blades that, when viewed from the side, resemble the pages of a book. Another interesting feature is that Kyanite has two distinct hardness ratings - when scratched on the parallel, its hardness is 4.5; when scratched on the perpendicular axis, the hardness is 6.5. The most popular color of Kyanite is blue, but it may also be black, gray, green or orange.
Kyanite aligns all of the chakras, and can be used to open them as well. Kyanite also aligns all layers of the aura. This makes Kyanite an excellent choice for any type of balance or energy work.
Kyanite transmits and amplifies high-frequency energies, making it a great stone for attunements and meditation. Kyanite brings a calming, tranquilizing energy to the body. Kyanite clears and calms you in preparation for meditation, and assists in receiving intuitive and psychic thoughts, as well as dream recall. Kyanite restores Qi (or Ki) to the physical body, and balances yin/yang energies.
Please Note: Although Kyanite may not need clearing/cleansing as often as most crystals, we suggest clearing your Kyanite as often as is needed, based on (1) the amount of use it gets (how hard is your crystal working for you?) and (2) the amount of energy that your crystal has been exposed to over a period of time. When clearing your crystals, always make sure that your intent is clearly stated, so the crystal knows that it is being given some time off and needs to recharge itself.
