Pearls are more susceptible than gems and need special treatment. Certainly, a good necklace must be tied with silk thread and knotted up in between pearls.
However:
- Protect them from excessive heat and flame, acids, alcohol, abrasion and sweat. At a fire they will burn and break. Their colour changes, they become brown, they dehydrate, crack and break.
- Hairsprays and perfume can make pearls lose their luster. Spray your hair and put your scent some time before putting on your jewelry.
- Do not wear your pearl necklace at the pool or the sea, chlorine and salt may alter its colour.
- Clean your pearls with a dry, clean and soft cloth. Never touch them with hands smeared with cream, cosmetics or liquid cleaning soaps.
