Description
Black onyx is a chalcedony traditionally associated with protection, grounding and strength, although these are cultural meanings rather than proven effects. At roughly Mohs 6.5–7 it is durable enough for necklaces, where impact risk is lower than in rings. Natural black chalcedony is uncommon and much commercial material is treated, so professional gem identification is preferable to home tests. Pendant chains commonly range from short 40–45 cm styles to longer lengths; clean gently and avoid chemicals.
