Gold becomes "silver" and market supervision "verifies the real body"
News from this newspaper (Reporter Wang Wei) Recently, the Shunyi District Market Supervision and Administration Bureau conducted a consumer dispute mediation: consumers bought a gold ring and wore it for 3 days, it turned silver, and consumers believed that the merchants were adulterated.
After receiving the complaint, law enforcement officers immediately learned about the situation and carried out relevant inspections.
During the investigation, an operation of the merchant turned the "silver" back into gold on the spot. What happened?
Recently, Ms. Mao, a citizen, complained that on March 16, she purchased a pure gold ring at a gold jewelry counter in a shopping mall, with a net weight of 9.13 grams and an amount of 4,926 yuan. After wearing it for 3 days, the ring turned silver.
Ms. Mao believed that the ring was impurity, and the merchant was adulterated, and asked to coordinate the return and refund for compensation and punish the merchant.
After receiving the complaint, law enforcement officers rushed to the scene to investigate and found that the merchant had valid business qualifications and a brand distribution authorization.
Subsequently, the law enforcement officers retrieved the inspection report of the same batch of gold products of the accused commodity, and the inspection results showed that the gold content was greater than 999.5‰, and no illegal act of operating and selling fake and shoddy goods was found by the accused subject.
Since it is not a fake, why does the gold ring turn silver?
After consulting with relevant professionals, law enforcement officers learned that the gold jewelry may have been exposed to chemicals such as disinfectants and hair dyes to cause discoloration. Generally, the gold color can be restored after burning and cleaning.
Subsequently, law enforcement officers organized Ms. Mao and the merchant to mediate.
At the scene, with the consent of Ms. Mao, the ring was cleaned and fired, and the ring returned to its original color on the spot.
The sales staff once again reminded consumers of maintenance precautions, and Ms. Mao also said that she would pay more attention to wearing it in the future.
In the end, the two parties reached an agreement on this consumer dispute.
The market supervision department reminds consumers that gold jewelry is a precious metal jewelry. After contact with substances containing mercury, lead and other elements, the surface will be discolored or oxidized. For example, the surface of gold will turn white when exposed to mercury.
Minimize exposure to the above-mentioned related substances when wearing jewelry. If the jewelry turns white, bring the sales receipt and jewelry to the purchase store for professional cleaning and firing, and then it can return to its true color.
