Gold verification for authenticity Visual inspection All gold jewelry has a special marking, which confirms the authenticity of the jewelry.

Real gold will sound ringing and pure, reminiscent of the sound of crystal. But we do not recommend using this method, as it is not suitable for all jewelry, as chains and bracelets cannot be checked in this way, and in jewelry with stones, stones can simply fall out. Vinegar Testing Put the gold jewelry in a glass with a little vinegar for 3-5 minutes.
