Like rainbows in general, rainbow crystals bring energies of hope and positivity. Rainbow crystals help one deal with and/or draw out negativity. They can lighten one's mood and bring happiness. They are also used to remove negative energy from a person, environment, or situation. They are excellent for people dealing with grief or depression and can help lift these weights from a person. They can help one see the positive in suffering or illness. They can be used in healing with any or all chakras.
