What is the reason for the ring to fade?

Only wear three days of jewelry, white spots

According to "If Ruo Ruo ___" introduced, on the evening of May 19, I bought a gold ring in Chow Tai Fook Fuzhou South Back Street Store. After wearing it for three days, there was a clear white spot on the surface of the ring (pictured). Then she posted the relevant photos on Weibo. From the close-up photo of the ring she uploaded, a white spot on the surface of the ring is particularly conspicuous, which is in stark contrast to the golden yellow in other positions.

She hopes that the jewelry store can explain what is going on, and she will give this issue to "Chow Tai Fook".

In the evening and yesterday morning, this Weibo was forwarded 225 times, and the evaluation reached hundreds of articles - "Is this the legendary silver-plated ring?" Some people do not believe that big brands such as Chow Tai Fook will sell fakes. The jewellery industry practitioners said that "it is possible to encounter mercury in cosmetics, just burn it with fire." "Chow Tai Fook" also responded that it would arrange for someone to follow up on this matter.

Yesterday, the reporter found that the gold counter of Chow Tai Fook South Back Street store has not sold this ring. The staff said that they had sold before and are now out of stock.

The disappearance of white spots after fire is speculated to be mercury pollution.

According to the staff, the consumer's problem has been solved. Yesterday, the consumer and the Dongjiekou jewelry inspection station tested the ring. The result showed that the jewelry had no quality problems.

The reporter then contacted “If Ruo Ruo ___”, she said that she would explain the progress of the matter on Weibo.

Yesterday afternoon, she sent Weibo: "In the morning, I went to the inspection agency with my friends. The result is true." Her test showed that the ring weighed 1.92 grams and the gold content was 99.9%. According to the regulations, the gold content of the gold is not less than 99%, which means that the color of the ring is no problem.

Secretary-General Wang of the Provincial Gemstone Association said that if the situation encountered is ___, the situation is mercury (ie mercury) pollution. After heating with the professional tools of the jewelry store, the white spots will disappear, not a quality problem. At present, the consumer's ring has been restored to golden yellow after being burned in a jewelry store.

According to reports, some whitening cosmetics contain mercury, and the contact of mercury with gold will turn gold into white.
