Pearl daily maintenance?
1, pearl jewelry should be stored separately: the Mohs hardness of pearls is only 3. Putting pearls together with other jewelry will undoubtedly scratch the surface of pearls, so it is best to store pearl jewelry in a velvet box alone.
2. Let pearls breathe air: pearls need to breathe air, so even if we put them in the safe, we should take them out once a quarter to let them breathe fresh air, otherwise they will become yellow-faced women in the safe.
3. Wear pearl jewelry after makeup: Any skin care products, perfumes and cosmetics will corrode the organic gems of pearls, so it is recommended that women wear pearl jewelry after makeup to prevent the pearl surface from being damaged by chemicals and losing its luster.
