Silver Jewelry Profits On March 4th, the Fujian Provincial Quality Supervision Bureau released the results of a random inspection on the quality of precious metal products for jewelry. Among the 18 precious metal jewelry samples with unqualified purity, silver jewelry accounted for 10 pieces, and some of the jewelry marked with pure silver were even 'Fake' with silver-plated surface and copper material inside. Silver jewelry is highly profitable. Sampling inspections found that among the unqualified silver jewelry, some of them are nominally thousand pure silver, that is, the purity is 999%. , But the actual purity is only 944%. , Some 925 silver jewelry (the purity is 925%.), the actual purity is only 850%. . Guo Qinghong, director of Fujian Jewelry, Jade and Precious Metals Testing Center, pointed out that compared to precious metals such as gold and platinum, the price of silver is much cheaper.'One kilogram of pure gold costs 200,000 yuan, but a kilogram of thousand pure silver only costs a few thousand yuan. 'But the sale of silver jewelry is very wide, and the sales volume is 8 or even 10 times higher than that of gold.' A company can sell dozens of tons of silver a year, even if one gram is a dime, the profit is huge. ''Some silver jewellery is plated with silver on the surface, and the fineness of the optically inspected surface is a thousand feet silver, but in fact it is mixed with other metals such as copper, which can only be found by other methods. 'In the inspection room of the Fujian Jewelry, Jade and Precious Metals Inspection Center, the reporter saw a beautiful bracelet with a nominal name of one thousand pure silver. The surface was found to be pure silver through X-ray fluorescence detection. However, the inspector used the density method to detect the bracelet metal.

The original price is 1,380 yuan, and the current price is 50% off. There is no sign on the ring. The clerk said it was an 18k gold ring with natural'Malay Jade'. However, the reporter carefully looked at the mark on the ring and found that the label was '18kgp'. When the reporter asked what this'gp' meant, the clerk changed his words and said it was'mixed gold, 18k is not pure gold'. gp is gold-plated or gold-clad jewelry mark Guo Qinghong, director of Fujian Jewelry, Jade and Precious Metal Testing Center, said that in fact,'gp' means gold-plated, and many people don't know the meaning, and they are often deceived. According to the reporter's understanding, the gp in '18kgp' is the mark of gold-plated or gold-clad jewelry. The 18k in front refers to the gold content of the outer gold-plated layer, and the 18k gold refers to the purity of 750%. Of gold. The Provincial Bureau of Quality Supervision also found that some production and processing companies are selling rings of thousand pure gold and 925 silver inlaid with b-cargo jade (bleached and glued treated jade). They only write '925 silver ring' and'thousand gold ring', but do not deal with jade. Logo.
