Black Moonstone has a strong energy to aid you to connect to the Divine Feminine during meditation.
Like the lovely rainbow moonstone crystals they resonate within the highest chakras, which may assist with the development of psychic gifts.
Their vibration is effective within the sacral or navel chakra to help with the emergence of fresh and novel ideas.
They also make a good connection within the base and earth chakras to stimulate grounding and give protection.
They are powerful used in meditation as they connect you to the specific spirit guides you may need to assist you, and also provide psychic protection.
