One of the most important cleansing crystals. Kyanite acts as a filter, it removes unwanted and harmful energies without completely de-energising the area it is used in. Kyanite is typically blue but it comes in a wide variety of colours. Different colours have slightly different purposes. Blue kyanite is associated with meditation -- it filters out unhelpful and annoying external stimuli. Black kyanite filters out ill-intent and ill-considered words and deeds. Orange Kyanite brings strength and helps filter out feelings of fear or worry.
