Will rose gold necklaces fade? 2 Why do gold-plated necklaces turn black? It’s because the gold plating is oxidized. Gold plating is divided into two categories, one is gold plating on homogeneous materials, and the other is gold plating on heterogeneous materials. Gold plating Homogenous materials Gold plating refers to gold plating the surface of gold jewelry. Its significance is to improve the brightness and color of jewelry. Gold plating of heterogeneous materials refers to gold plating on the surface of non-gold materials, such as gold plating on silver and gold plating on copper. How to clean a gold-plated necklace that turns black? 1. Toothpaste is a good helper for removing blackness. Toothpaste is rich in fine calcium carbonate particles that rub away oxides from the surface. Find a toothbrush, dip it in some toothpaste and rub it patiently for a while, then rinse it off with water. 2. It should be noted that after scrubbing with toothpaste, you must wash it with clean water. It is best to wash it with pure water. Do not wash it with chlorine-disinfected tap water. If a gold-plated product has been stored for a long time, the surface of the gold layer will be oxidized and blackened by the metal inside, instead of the gold coating on the surface being oxidized. Because the gold-plated layer is very thin, the metal inside will easily damage the surface coating. If you want to restore the product It turns out that the gold color can only be obtained by sending the product to an electroplating processing factory for re-plating. How to maintain gold-plated necklaces: 1. Store the jewelry separately in a jewelry box or suede bag to prevent scratches on other jewelry. 2. Please do not wear it when doing housework, gardening, and other types of heavy work or physical activities. When wearing gold-plated jewelry, do not come into contact with bleaching or harsh chemicals. 3. To clean your jewelry regularly, use a commercially available jewelry cleaner, or soak it in a solution of soap and warm water and wipe it gently with a soft cloth. Clean every six months. 4. If there are visible scratches or a natural oxide layer appears on the surface, please take the jewelry to a qualified jeweler for polishing. A scratch is simply a displacement of metal, it does not reduce in volume. 5. Have the jewelry adjusted, resized, polished and cleaned by a qualified jeweler. Make sure the jeweler has trained fitters.
