I was so excited to locate these black kyanite pendants! Kyanite supports the chakras by aligning them and clearing energetic pathways. It will also enhance psychic abilities and intuition as well as assist with spiritual guidance and connection. Black kyanite has the additional property of grounding when aligning the chakras. Kyanite is one crystal that never requires cleansing. If you are new to kyanite, please be aware of its very fragile nature and handle with care. The small measures approximately 1 inch, the medium - 1 1/2 inches. Both size are gold-plated.
