} Wearing and Storage of Pearls:
1. When wearing pearls, avoid contact with acid-alkaline substances such as shower gel, shampoo, soap, perfume, hair gel, nail polish, and cosmetics. Otherwise, the beautiful pearl luster will become dull and even the pearl will yellow and peel.
2. The hardness of pearl is low, the hardness of Mohs' hardness is 3.5~4, and the articles with greater hardness than it may scratch the pearl. The sand entrained in the dust can also be scratched on the surface. Avoid friction with hard objects during wear and storage. . Store as much as possible and store it separately or package it properly. Do not mix it with other jewelry.
3. When pearl jewellery is not used, the surface of the pearl must be cleaned. Cleaning to remove sweat can keep the pearl surface clean. Clean with a soft cotton cloth dampened with water.
4. Pearls have moisture and cannot be stored together with desiccants to prevent the pearls from becoming too dry and yellow. Stored in a cool place, the pearls can maintain proper humidity and cannot be exposed to high temperatures.
