Real onyx generally has a consistent, smooth color with natural banding and a glossy finish. To check, conduct a scratch test with a knife; real onyx is relatively soft and might scratch. Fake onyx often shows bubbles or lines if made of glass or resin. Also, consider the temperature test: real onyx feels cool to the touch compared to fakes which warm quickly.
