- Clean your pearl jewelry with a soft, damp cloth. The cloth should not be too wet. When you buy pearl jewelry, then there include a soft cloth with the jewelry which can use for cleaning purposes.
- Keep your pearl jewelry in a separate pouch or box. A pearl’s surface is not very hard, so it’s easy to be damaged by other pieces of jewelry if you store them together. According to the Mohs hardness scale, pearls, or Calcite, are only on level 3, which is right between a fingernail and a copper penny. Diamonds are on level 10. Wrap pearls with a soft cloth and store separately.
- Pearls are living organisms, so they need fresh air to breathe. Take them out of their storage space and wear at least once every season; otherwise, the color of the pearls will quickly start to change over time.
- When dressing and undressing, put on your pearl jewelry last and take them off first. This will help them keep their luster. Cosmetics such as skin products, makeup, and perfume may have an erosive effect on pearls. Pearls can absorb these chemicals, so try not to let it get in contact with cosmetics.
- Don’t use direct water to clean the pearl’s surface. Pearls can absorb the water which is difficult to dry out again and can, therefore, cause fermentation inside the pearls. Fermentation will cause the pearls to change color and lose their luster. Clean as described in point 1 above.
- Don’t let the pearls lie under direct sunlight for a prolonged period or store them in a too dry place, as this will cause pearls to lose the water inside. Since pearls consist of only 4% water, drying out will cause them to lose their luster.
- During storage, don’t hang pearl necklaces but rather store them inside a pouch lying flat. The silk thread may become slack if hung for an extended period. Check the thread every two to three years to see if the thread is still in good condition and change if necessary. The last thing you want is for the thread to break and lose your pearl beads.
- Don’t give up on your pearls if they start to turn yellow. Pearls can be immersed in diluted hydrochloric acid, which will cause the outside nacre layers to melt off so the inside luster can come out again. Your necklace will look new again. If you don’t know how to do this, rather leave it to the professionals!
