1. Keep away from acidic substances. Many people wear pearl jewelry close to their skin, take it off and put it directly into a box for collection. After a period of time, they find that the luster of pearls is not as good as before, in fact, because sweat secreted by human skin is also weakly acidic substances. Therefore, after wearing it, it should be wiped clean before it can be put into the box.
2. Stay away from heat sources. Protein and water in pearls are important components. High temperature will evaporate water, age protein and seriously damage the structure of pearls, ranging from yellowing and darkening to complete fragmentation. High temperature will also dissolve or age the glue inlaid with auxiliary pearls, causing pearls to fall off.
3. Keep away from bleached substances and environments. The beautiful color of pearls is caused by organic pigments. When encountering bleaching substances, such as 84 disinfectant, hydrogen peroxide and many daily detergents, they will be easily bleached and faded, especially gold pearls and black pearls.
