A powerfully protective stone, Black Onyx absorbs and transforms negative energy and helps to prevent the drain of personal energy. Black Onyx aids in the development of emotional and physical strength and stamina, especially when support is needed during times of stress, confusion, or grief. Black Onyx may also foster wise decision-making. It is wonderful for meditation and dreaming. When using Black Onyx for either of these purposes, it is recommended to use a secondary grounding stone in combination with the Onyx.
