The pearl luster is charming and can be made into rings, pendants and other styles for sale. Em particular, white pearls have a large market share, are versatile styles, and have many people. The biggest problem with pearls is yellowing and peeling. How did this happen? How should we deal with it? The editor of Baolong.com will help you.
If the pearl is not processed by bleaching and dyeing, the so-called original pearl is not easy to change color. Por exemplo, the four large pearls on the phoenix crown of Empress Dowager Cixi of the Qing Dynasty were discovered in Xi’an in 1993. They were still dazzling and were worth 100,000 yuan at that time.
If the color of the pearl is not white and uneven, it needs to be processed and dyed. It is the liquid used in bleaching and dyeing that destroys the structure of the nacre and makes it easy to fall off. Ao mesmo tempo, the chemicals are easy to deteriorate and make the pearl yellow. Além disso, thin skin is easier to peel; improper maintenance is also a factor that causes pearls to yellow and peel.
Então, what should I do if pearl jewelry turns yellow after a long time? How to restore it?
Although the color of the pearl is very beautiful, it cannot stand the test of a long time. Geralmente, after a few decades, pearls will turn into ordinary yellow and lose their beautiful pearl luster. This is what the saying goes.
Why does pearl jewelry turn yellow after being used for a long time? This is mainly because the physical properties of the aragonite mineral that make up pearls are unstable. Over time, it will become ordinary calcite. Although aragonite and calcite have the same chemical composition, their crystalline form and luster are quite different. This is why the pearl changes color. After the pearl turns yellow, there are some remedies, aquilo é, soaking in dilute hydrochloric acid can dissolve the yellow shell, so that the pearl reappears its brilliant, rustic and charming color. But if the color becomes very strong, it will be difficult to reverse.
