Pearls are known as the "Queen of Jewelry." Their magnificent colors and graceful and elegant shapes make them stand out and become unique in the world of jewelry. Pearls are made from mother-of-pearls, and their luster and bead body have a certain lifespan. When exposed to the air for a long time, the nacre layer will be oxidized, and its color will change. Its value preservation period is generally about 100 years.
But there are exceptions. Australian archaeologists discovered a rare natural pearl while conducting archaeological excavations at Aboriginal sites. Carbon dating confirmed that this is a 2,000-year-old natural seawater pearl. The color is pink and gold, the diameter is 5 mm, close to a perfect circle, and has a certain luster. The discovery of this "cultural relic" pearl shows that natural pearls can be preserved for much longer than we imagined.
Pay attention to the following aspects when taking care of pearls:
Pearls are most opposed to water, so do not bathe or exercise while wearing pearls, as water will seep into the interior of the pearl from the bead holes and cause the bead layer to detach. If the pearls accidentally come into contact with water, they should be wiped dry with a soft cotton cloth and then placed in a ventilated place to dry in the shade.
In addition to avoiding water, pearls also avoid heat. Pearls should only be exposed to high temperatures for a short period. At the same time, pearls should prevent acid and alkali. Pearl jewelry should not be worn in the kitchen because oil fumes are acidic. Wipe pearls with a soft, dry cloth. Do not let sweat or body oils stay on the surface of pearls for a long time. When there are stains on the pearl surface that need to be cleaned, you should first wipe them with a soft cotton cloth dipped in clean water, then wipe off the water on the pearl surface and place it in a ventilated place to dry in the shade. Remember not to use detergent. Do not put pearls together with sharp objects to avoid scratching the surface of the pearls.
Although the price of pearls on the market is currently on the rise due to factors such as shelf life and difficulty in preservation, collectors need to be cautious when investing in pearls.
