Why does the ring change color after more than 10 days

Question: I bought an electroplated K gold, and I only wore it for more than 10 days. I found that many places began to fade. Now the colors are all black and ugly, so I don't dare to wear it. Answer: Not only that, almost all jewelry must be electroplated, and the quality of electroplating directly affects the wearing time of the jewelry. The color of your ring began to fade after more than 10 days. The reasons are as follows: 1. The plating layer of the ring is very thin: some manufacturers, in order to reduce the cost, the plating thickness is less than half of the normal thickness, and there is no increase in the protective layer, and it is exposed to sweat. For corrosive things, the electroplating layer will quickly fade; 2 The storage time of the ring is too long: some rings were produced a few years ago, because they were not sold, they have been stored in the warehouse, and packaged when they are cleared a few years later Processing, just bought by you, just imagine, how long can the validity period of plating be guaranteed? 3 Another point is easily overlooked. Rings that have been electroplated must not come into contact with corrosive substances such as chemicals. Remove the ring when you sweat, wash your hands and take a shower.
