Pearl is a high-grade ornament, so we should pay attention to daily maintenance. The composition of pearl is calcium carbonate containing organic matter, which has poor chemical stability and can be dissolved in acid and alkali. Therefore, the following points should be noted during maintenance:

1. Do not touch moth balls, detergents, coffee, perfume, oil, salt, alcohol, vinegar and dirt, and do not touch organic solvents such as banana oil, because they will destroy the internal structure of pearls and produce black and yellow beads. If wine or coffee spills on pearls, rinse them with clear water immediately and dry them with a soft cloth.

2. People sweat a lot in summer, so it is not appropriate to wear pearl necklaces. When pearl jewelry is not worn, gently wash it with high-grade neutral soap or detergent and dry it to ensure the lasting brightness of pearl jewelry. Avoid exposure to bright light.

3. When not in use, carefully store it in a jewelry box and keep it moist (don't put it in a plastic bag). It is best not to put it with other jewelry to avoid scratching the pearl surface.

4. The hardness of pearls is very low. White pearls will turn yellow and their luster will become worse if worn for a long time. It can be bleached with 1% ~ 1.5% hydrogen peroxide, but be careful not to bleach too much, otherwise it will lose its luster.

5. In daily wear of pearl jewelry, always check whether the string of jewelry is firm. If it is damaged or falls off, it should be repaired in time to avoid loss.

6. There is a saying in the jewelry circle that if you brush jewelry with a toothbrush dipped in toothpaste, the jewelry you can use looks as bright as new. It is necessary to clean jewelry, but Yahao is not ideal, because toothpaste contains fine abrasive particles with high hardness, which are very fine but the hardness is as high as six or seven degrees (similar to that of crystal), so cleaning jewelry with toothpaste will damage the surface of gems with hardness lower than that of crystal, especially pearls, gold and K gold; Pearls are absolutely avoided, and the most correct washing solution should be diluted neutral surfactant (such as salad dressing and baby shampoo).

7. Don't touch jewelry often. It seems simple, but it is not easy to wear. Many people can't help touching the surface of a gem when they see its beauty and charm. This will actually affect the luster and brightness of the gem.

From time to time, the human body excretes sweat and oil on the skin surface, and the hand is the most accessible part of the body, so the oil on the skin often pollutes the surface of the hand. When you touch a gem with your hand, the grease on your hand is easy to stay on the gem, which affects the luster and brightness of the gem. In particular, diamonds are lipophilic gems, and their surfaces are easily contaminated with grease, which greatly affects their luster. However, jade white jade belongs to * * * body structure. Frequent touching can make jade more moist and lovely.

8. Tap water will spoil the luster of pearls. Some people want to wash and maintain pearls after wearing them several times. I don't know that cleaning with tap water for a short time has little effect on jewelry, but if it is used to soak pearls, it is absolutely impossible. Because there is a fixed content of chlorine (C 1) in tap water, it will destroy the luster of pearl surface. In fact, mineral water is the best way to soak and wash pearls.

In addition, after wearing pearls, they should be cleaned and maintained before being sent to the safe deposit box in the bank, so as to avoid discoloration of pearls due to dirt accumulation for too long in the future. Moreover, the storage conditions of safe deposit boxes for cash and documents kept by banks are not suitable for tidal gems such as pearls and protein, so they must be taken out every once in a while, soaked in water for maintenance and supplemented with humidity.

What should I do if I encounter the phenomenon of yellow pearl necklace?

If you don't keep it well, the pearl necklace will turn yellow Is there any way to turn white?

Some pearl jewelry worn or stored by ancestors for more than ten years may turn dull yellow.

After the yellow shell is dissolved, take out the pearl quickly, wash it with clear water and dry it, and the pearl will regain its luster. However, special attention should be paid not to soak in horrible hydrochloric acid for too long to prevent pearls from being damaged. Of course, if the color becomes very thick, it is difficult to reverse it. For black, dull and heavily dyed pearl jewelry, it can also be soaked in 10% salt water, rinsed with 3% dilute hydrochloric acid solution, and then rinsed with clear water, which can also restore luster.
