Many people like to buy ** jewelry, which is not only beautiful, but also retains its value. However, as an ordinary consumer, you may not be able to identify whether the ** you buy is real, in order to ensure that you can buy**, most people will choose to buy in a physical store. But Ms. Fan from Hangzhou just bought the bracelet for half a month and it faded, did she buy a fake?
Ms. Fan from Hangzhou took a fancy to a **Pixiu bracelet worth 1,960 yuan in a jewelry store, but it took less than half a month to startIt was found that the tail of the **Pixiu had lost color。At this time, Ms. Fan's freshness had not yet passed, and she was very anxious when she encountered such a thing, and she suspected that she had purchased a fake **. I found a reporter who wanted to ask for a reasonable explanation. The reporter accompanied Ms. Fan to find the jewelry she bought, and the store manager swore that the bracelet was absolutely real, and there would be no problem with the qualityIt is because Ms. Fan may have used some products that contain weak alkali or weak acid, which will cause fadingThere are many reasons why a bracelet can fade, and this can also happen when swimming with a bracelet. However, Ms. Fan said that she usually takes off the bracelet even in the shower, so she does not think it is caused by improper personal wear. 
Both sides have their own opinions, and the store manager insists that there is absolutely no problem with this bracelet, and there is a national inspection stamp on it, so please rest assured that Ms. Fan cannot accept such a statement. For this reason, the reporter consulted relevant experts and found a way to identify it, that is, to burn it with fire. As long as it is a real **, it is not afraid of fire, but it is getting brighter and brighter, and the store manager also agreed to do the test on the spot. Although Pixiu is identified as true in this way, Ms. Fan still thinks that there is a quality problem with this braceletTherefore, I hope that the store manager can handle the return application for himself. The store manager finally agreed to Ms. Fan's request for a refund, and generously said that she would pay for the depreciation herself. We have said a lot of news about the fading of jewelry this year, in fact, it is normal to appear in the news, and the final result is also happy, ** jewelry in the wearing process, some in addition to the fading mentioned above, there may also be blackening, rust, whitening and other situations, let's talk about these situations and treatments. RustWhy do ** jewelry bought in jewelry stores have tawny spots? This is because during the processing process, gold jewellery encounters iron filings in the air, and iron filings must be avoided during processing. After iron oxidation, it will form a red buildup on the surface, and there will be "rust" that consumers mistakenly think. After rusting, don't worry, thinking that you can't get rid of it, in fact, you only need to simply clean the gold jewelry. 
WhiteningThe symbol of the chemical element is AU, which has good physical properties, stable chemical properties, high ductility and scarce quantityEncounters with mercury can cause chemical reactions, especially in cosmetics that women come into contact with contain trace amounts of mercury, which can cause jewelry to turn white. 
There is also a situation where**jewelry and platinum jewelry are stacked together and rubbed against each other, **jewelry will rub against platinum and white, in this case, it is possible to plane with an agate knife to restore the brightness, but because of the fear of damaging **jewelry, it is recommended to carry out it under the guidance of professionals. Blacken**The nature is very stable, but it will turn black when it encounters lead, and some cosmetics or hair dyes contain trace amounts of lead, which is easy to turn black if you accidentally touch gold jewelry. Therefore, it is best to avoid touching gold jewelry when rubbing makeup. 
In this case, you can use gasoline spray wheel heating for treatment, because the melting point of mercury and lead is very low, in the spray wheel heating treatment, it will volatilize, so that the ** jewelry will return to its original appearance. In addition, the blackening or fading of jewelry is also closely related to human sweat - 99% of human sweat is water, and the other 1% is about 1% of waste and harmful substances in the human body, such as chlorinated, lactic acid, urea ammonia, etc. When these substances come into contact with silver and copper in jewelry, they will undergo a chemical reaction to produce silver chloride and copper sulfide, and present deep black chemical salts, which will have a certain impact on the appearance of gold jewelry. Some cosmetics or hair dyes contain trace amounts of lead, which can turn black if you accidentally touch gold jewelry. In view of this situation, it is best not to wear ** jewelry when applying makeup or dyeing hair to avoid future troubles. ** Maintenance1. Toothpaste can make our teeth white, and it can also make **jewelry shine as new, and toothpaste can remove dirt on the surface of **jewelry. But this method is not very good, because the toothpaste contains abrasive particles, if you often use toothpaste to clean the ** jewelry will reduce the weight of the gold jewelry, causing unnecessary losses. 2. Ammonia has a very effective effect on the cleaning of the surface, and the method of helping ammonia cleaning is also very simple, first take a bottle and add pure water to it, then drop a few drops of ammonia into it, and finally put in the jewelry, shake it vigorously a few times and then take out the gold jewelry and wipe it dry with a soft cloth. 
3. First take 1000 ml of warm boiled water, then add 200 ml of glacial acetic acid to make an aqueous solution, then put ** jewelry into the made aqueous solution and soak it for 10 minutes, then gently scrub it with a soft brush dipped in hot water, and finally rinse it with water. It is best to use a cotton ball dipped in soapy water and anhydrous alcohol to scrub, so that the cleaned ** jewelry will become gorgeous. 
4. Brush with soapy water mixed with a little alcohol, rinse and wipe dry with a soft cloth. Or use a flannel cloth dipped in toothpaste and gently sassafras until it is shiny.

If there is a black silver film on the surface of the jewelry, the more commonly used method is: 2 grams of salt, 7 grams of baking soda, 8 grams of bleaching powder, 60 ml of water, prepare a gold cleaning agent, put the gold jewelry in a bowl, pour the cleaning agent, two hours later, take out the gold jewelry, rinse it with water, and then wipe it with a soft cloth. 6.
