Dioptase is a stone of healing that has a refreshing energy. It can help heal in many ways emotionally, including helping get one started clearing one's issues, and releasing negative emotions and stress. It promotes healing from abuse, neglect, sadness, and despair. It is called a stone of "Living in the Moment" because it helps one overcome these hurtful past energies and find the joy of the current moment, bring calm, confidence, and self-worth.
Spiritually, dioptase is good for alignment and attunement with the spiritual energies of your choice.
Physically, dioptase is used in crystal healing for heart burn, physical heart problems, meniere's disease, and deep healing in general. Please note that healing crystal meanings are spiritual supports to healing and are not prescriptions or healthcare information.
Dioptase is related to the heart chakra.
Dioptase contains copper, which though a necessarily micronutrient can cause copper toxicity in large amounts. I suggest using the indirect method if creating gem elixirs with this stone.
