Gold-plated stainless steel tarnishes with time. It is a metal and prone to fading with continuous exposure to harsh environments. The chromium film on the outer side of stainless steel protects it for a while. But, it needs proper polishing, care, and maintenance to shine. Gold-plated designs add an extra protective layer. Besides, the electroplating process allows the jewelry to have luster. But, the gold layer oxidizes and tarnishes, especially if it is fragile. Scratches on it fasten the tarnishing process.
