I believe many people have encountered this situation. Jewelry is shiny when it is just bought back, but it becomes dull after a long time. In fact, this happened because it was not properly maintained. So how to maintain different kinds of jewelry such as diamonds, gold and K gold?
The most beautiful thing about a diamond is that it shines brightly, but it will lose its original luster if worn for a long time. This is because diamond is a kind of oil-loving and hydrophobic gem, so when wearing it, greasy skin, daily food and dust may attach to the surface of diamond, which makes the diamond lose its original luster and look gray.
When wearing diamonds, don't let the diamonds be contaminated with chemical cleaners with strong acid and alkali, so as to avoid leaving stains on the diamonds. If you wear it every day, it is best to wash the diamond once every two weeks, soak it in cold water, then brush it gently with a soft toothbrush, and finally dry it with a clean flannel.
When wearing gold jewelry, avoid direct contact with volatile substances such as perfume and hair gel, otherwise it will easily lead to the fading of gold jewelry. When swimming, remove the gold ornaments to avoid chemical reaction on the surface after contact with seawater or pool water.
