Kyanite is one of only two minerals (the other being citrine) that do not retain or build negative energies, making it excellent to aid in clearing and cleansing other crystals, as it doesn't need clearing or cleansing itself.
Wearing or using Kyanite can inspire loyalty, co-existence and fair treatment of others. It is very useful in working through disputes and repairing damaged relationships. In work situations Kyanite can help bridge the gap between different ideas and opinions, encouraging good communication and teamwork.
If you have lost your way or your direction in life, Kyanite is very useful in helping you sort your thoughts and dreams and figure out where you want to go. It can also help break cycles of self destructive behavior. Wear over the heart to help examine all aspects of yourself and provide guidance.
Just a side note, I have wire wrapped Kyanite healing pendants in my shop! These are high quality crystals that have been personally wrapped by me. Check them out! and use the code GRANDOPENING for free US shipping!
