People who wear silver jewelry often know that if the silver jewelry you wear for a certain period of time suddenly turns black, experienced people will tell you that there are some problems in your health. And when some people wear jade, they will find that their emeralds are getting dark. Isn't it that their emeralds are getting dark because of their bad health? The answer is of course no. There are many reasons for the discoloration of jade, let 's take a look at the Chinese jewelry investment network Xiaobian to see what are the reasons. 1, normal discoloration Some Tibetan friends will feel that their emeralds are more and more green, and they are more and more bright. What is the reason for this? Jade jewelry is in contact with human skin. The sweat of the human body penetrates into the mineral combination of jadeite, fills the gap between the jadeite mineral particles, increases the transparency of the jadeite, nourishes the jadeite, and the green of the jadeite is more obvious. Many people think that green is like living, and the president is the one who often says "human jade." In addition, the human body has a similar effect on polishing and polishing, and the refractive index and reflectivity of the light have changed, and it looks like the crack of the jade has healed. So the emeralds that wear them will look brighter and brighter. The more the emerald is worn, the better it is. It is a good thing, don't think too much. 2, faint yellowing If the jade is light and yellow, then it is recommended that you first obtain the authoritative appraisal department to see if it is A goods. If it is confirmed that it is A goods, it may be because of the jade species. Generally, after the relatively tender species have been worn for a long time, the crystal structure inside the jadeite is easy to change, and a lot of water will volatilize. It is no longer like the previous water, but will gradually fade and yellow, which is the saying of the jade. "phenomenon. The jade "variant" phenomenon is a natural phenomenon that occurs in all natural minerals. Therefore, this phenomenon is naturally not caused by poor health, but the change of jade itself, and the jade of the variety does not affect wearing. 3, improper maintenance Many Tibetans know that jadeite needs to be carefully maintained, but many people don't know how to maintain it. Many human hearsays, such as bleaching water, toothpaste, detergent and other cleaning agents to clean up jade, these methods are wrong. These cleaning agents contain chemicals that chemically react with some elements of the jadeite to corrode the surface of the jade, causing the jade to discolor. In addition, some jade will become dirty and discolored when not washed for a long time. Therefore, jade needs careful maintenance and regular maintenance. 4, the natural jade's "ç‘•ç–µ" exposed Natural jade is not all perfect, many of them are flawed, such as cracked, dirty, mottled and so on. Such jadeite not only affects the selling phase, but also greatly reduces the value. The merchants will polish the powder for this purpose, and the polishing powder is actually a kind of dyeing agent. Usually, after the manufacturer has used the polishing powder, the defects are completely covered by waxing and the like. After the customer wears it for a period of time, the wax on the surface seal gradually fades away. The original dirty spots of the jadeite slowly appear, that is, the jade is more and more black. 5, B + C goods color In fact, the most likely reason for the blackening of jade is to buy fake jade. If the body is not good, the jade will become black. This is nonsense. In fact, if the jade becomes black, it will affect people's health. Nowadays, many beautiful jadeites on the market are not natural A goods at all, and most of them are B and C goods that have been pickled. B goods are eroded by strong acid and alkali, their internal structure has been destroyed, and the texture has become loose. In order to cover up this phenomenon, organic rubber or inorganic glue is often used for filling. So the emerald discoloration is not necessarily a problem with your body!
