Pearls: Did you know that pearls are alive and can last more than a hundred years if they are worn? Indeed, pearls naturally hydrate in contact with air and the epidermis, which helps maintain their shine. They resist shocks quite well, but their surface is porous and can deteriorate.
Cultured pearls are soft and require special attention. They are particularly sensitive to chemical deterioration, especially by oils and salts from the skin.
To maintain them, pearls should be wiped with a chamois or flannel cloth after being worn and stored in a chamois designed for this purpose or in a velvet pouch after being cleaned.
Avoid careful contact with skincare creams, foundations, perfume, hair spray, alcohols, highly acidic water (swimming pools). Contact with other jewelry should also be avoided (on oneself and in the case).
