Crystal Guidance: Crystal Tips and Prescriptions - Anxiety. Top Recommended Crystals: Labradorite, Green Aventurine, or Lepidolite. Additional Crystal Recommendations: Rhodonite, Amethyst, or Kunzite. Affirmation: "I love and accept myself and I trust the process of life. I am safe." - From 'Heal Your Body' by Louise Hay. Anxiety is associated with the Root chakra, but I have personally found it very helpful to hold the crystal(s) at the Heart chakra.
