• Density : Approximately 3.6 to 3.7

• Luster : Vitreous to pearly

🌿 Properties and uses (lithotherapy):

Black cyanite is often used for its grounding and energetic protection properties:

• Would act as a cleaner of negative energies

• Would promote the balance of the chakras , especially the root chakra
