Cleansing and Recharging Methods of Kyanite Jewelry
The mystical purifier, water, is thought to flush out any negativity held within the gem stone. By washing your Kyanite Jewelry with water, you can make sure that all of the old, negative energy is released and returned to the ground. You might use pure river water or water that is running from the faucet to wash your Kyanite Ring or Kyanite Pendant. It is preferable to take a bowl of water and soak the stone in it for a few minutes. Your gemstone would be purified during this procedure, and it would also get fresh gemstone energies.
