Gold plating will tarnish. Gold plating refers to plating a layer of gold pigment on the surface of other metal jewelry by the electroplating method. The color is remarkably similar to gold, and it is impossible to distinguish gold and gold plating by color. The gold-plated material is not gold, so it will tarnish after wearing it for a long time. When wearing gold plated jewelry at ordinary times, we should pay attention to care and avoid friction; friction will make the plating of gold plated jewelry disappear. To avoid cosmetics, perfume, and other corrosive liquids will accelerate the fade.

how long dose gold plated jewelry last?

Let’s take three examples of gold-plated jewelry in our daily lives:

925 silver gold plated: Normally, if the 925 silver gold plated is worn correctly, it can be maintained for one year without fading. But suppose the 925 silver gold plated surface is stained with a lot of grease and sweat when wearing. In that case, the wearing time will be shortened, and the color will fade after about half a year or even earlier. We can maintain the 925 silver gold plated to delay its fading. In the maintenance of 925 silver gold plates, the surface of 925 silver gold plate can be wiped clean with a fine linen cloth or tissue paper with good water absorption performance to avoid the oil sweat staying too long, causing an impact on it. It can also clean the 925 silver gold plate by coating a layer of colorless and odorless nail polish on its surface and forming a protective film after drying to prevent the 925 silver gold plate from being eroded by foreign bodies and delay the fading.

Brass gold plated: Brass gold-plated jewelry can generally be worn for about three years. Time is easy to fade. During wearing, please pay attention to keep away from acidic and alkaline substances, including toner, soap, laundry detergent, and dishwashing liquid, to avoid accelerating its fading.

18K gold plated: 18K gold plated if the plating process is better than others time, and the daily wear process is also more attention, it can adhere to 5-10 years without fading; But if the plating process is general, everyday wear is not paid attention to, then it may be worn within a year will fade. If the coating on the surface of the 18K gold-plated material falls off, the jewelry can be sent to the merchant and re-coated to make it look bright and shiny.
