We’ve just added a new reference document to our site which covers the important subject of crystal toxicity. Grateful thanks to ACHO Principal Janelle Scialla for providing this informative extract from her student manual, The Advanced Crystal Therapist. Although most crystals we use as Crystal Healers are safe and non-toxic there are some exceptions. Make sure you know which stones need careful handling in your own collection. Always use non-toxic crystals if you are placing them in drinking water, or making gem essences by the direct method.
