Electroplating. Electrolysis refers to the breaking apart from a molecule by the means of the electrochemical reaction. Electroplating refers to the passage of current through the solution with metal such that it gets deposited on one of the electrodes. Electrolysis is good for carrying out the non-spontaneous chemical reactions.

Usually, the gold plating is connected to the anode (+ve charged electrode) of the circuit and the jewellery is kept at the cathode (-ve charged electrode). Both are kept immersed in a highly developed electrolytic bat (solution). At this stage, a DC current is supplied to the anode that oxidizes the gold atoms and dissolves them into the solution.
