Anything that is real gold plated is Anti tarnish in general and last longer than non plated material . but it needs to be taken care of well, so that the plating doesn’t go off. If the plating is scratched or removed due to wear and tear, then they will start tarnishing. So its best to take care of them well like wiping them if they come in contact with water, removing before sleep and workout.
