Does electroplated gold fade?
The drawback of gold plated jewelry is that the gold layer will fade and tarnish with time. This is because the molecules of the base metal will slowly travel to the top layer, showing signs of wear. However, with good and proper care, the gold plated layer can last for up for a year or even two.
How long does electroplated gold last?
