Crystal Guidance: Crystal Tips and Prescriptions - Back Pain. Top Recommended Crystals: Magnetite (also known as Lodestone), Hematite, or Lapis Lazuli. Additional Crystal Recommendations: Calcite (any color, but I feel Green or Blue would be best) or Fluorite. Hold the crystal to the site of pain as needed. You can tape the crystal to help hold it in place. Heating pads also work well to help relax the back muscles.
