   - **Metaphysical Properties:** In metaphysical beliefs, Black Onyx is associated with protection, grounding, and stability. It is believed to absorb and transform negative energy and promote inner strength and self-confidence.
   - **Decorative and Carving:** It is also used for decorative objects and carvings due to its smooth texture and ability to hold intricate designs.

5. **Care:** Black Onyx is relatively durable but should be handled with care to avoid scratching or chipping. It can be cleaned with mild soap and water.

Overall, Black Onyx is valued for its rich black color and symbolic associations with strength and protection in various cultures and spiritual traditions.
