Emotions and attitude are uplifted and positively affected by blue calcite. Blue calcite is very good at harmonizing yin and yang, the positive and negative elements of the universe, as well as for balancing emotional, physical, and intellectual energy. This stone has a highly relaxing, stress-relieving effect since it vibrates at a slower frequency. When you're recovering or mending, blue calcite is the ideal crystal to utilize because it promotes physical recovery.
