How is it possible for our gold plated jewelry to be waterproof? Reed the answer below ⬇️ Our jewelry has a highly special coating called PVD (Physical Vapor Deposition). The technique involves “blasting” 18 karat gold onto another metal at a high temperature. During the process, the material moves from a condensed vapor phase that to a thin solid film. PVD coatings are considered harder and more corrosion resistant than other metal coatings that use the electroplating process. The PVD coating a
