Spiritual, Metaphysical and Healing Properties

Kyanite is one of the most powerful minerals of its kind. It is thought to instantaneously align all chakras, and with intention, to open them. Blue kyanite stimulates communication and psychic awareness on all levels. It is a calming stone, dispelling anger and frustration, and promoting clarity.

Kyanite is especially useful in facilitating meditation; its energy is gentle, leading to calming, clearing, and balancing. It dispels energy blockages.

This is one of the few minerals that never needs cleansing or clearing. It will not accumulate or retain negative energy or vibrations.
