To tell if black onyx is real or fake: Examine its color consistency; real onyx is uniformly black with no gray patches. Check the weight; genuine onyx is heavier than glass or plastic. Conduct a scratch test using a piece of glass; true onyx, being harder, should not scratch easily. Finally, look for polished surfaces; real onyx will have a high sheen due to its natural glossiness.
