Black onyx is a fortress of shadow, forged to guard the secrets of the soul! Black onyx cabochons offer excellent durability (6.5 to 7 on the Mohs scale) and aesthetic versatility for jewelry making. They can be used in necklaces, pendants and rings. The stone acts as a barrier against negative energies, psychic attacks, and everyday stress by anchoring the root chakra. It is also known to promote inner resilience, self-control, and the release of past traumas or unwanted attachments. Its hardness ensures it handles daily wear-and-tear beautifully without chipping easily.
