Gold plating is the addition of features in a project that were not requested within the Project Scope. Project Scope Creep comes from the customer side, where as Gold Plating is introduced by the Project Team. Gold plating can be a good or a bad thing for a project, as the customer may or may not accept the change.
If the customer accepts the change, all is good, except that this may have cost the project some time or money. If the customer does not accept the Gold Plating, then remediation work may have to take place to back out the changes to the original scope, which will potentially cost both time and money.
