This stone is very soothing. In general, blue calcite and aragonite helps remove blockages in the third eye and stimulates one's intuitive and psychic abilities. It can aid in developing inner vision and clairvoyance. It can help one be more sensitive to the thoughts of others and it enhances telepathy and psychic communication over long distances.
