Black onyx is a stone known throughout the world for possessing wonderful spiritual qualities. From warding off the evil eye to helping with stress, black onyx can help stabilize emotions. As a polished, conical bob for a pendulum, this makes it good for providing a neutral position that can help you find answers without the energies of your emotions influencing your dowsing. Measuring 1 1/2 inch, the bob comes at the end of a 8 inch chain, decorated with stones representing the 7 Chakras to aid you in channeling your energy.
