18k gold plating will fade. 18k gold plating is stable in performance, but 18k gold plating is only plated on the surface of the object, which will wear to varying degrees after a long time, and 18k gold plating will fade.
If the gold-plated layer of 18k gold falls off, the faded jewelry can be taken to the jewelry store for re-electroplating 18k gold, and the original bright and charming color of the jewelry can be restored.
When wearing electroplated 18k gold jewelry, avoid contact with cosmetics, perfumes, detergents and other supplies, otherwise the chemical components in such supplies will corrode the jewelry and the jewelry will fade easily.
