Jewelry has always been regarded as a "soft" of luxury goods and even value-protected products. However, the reporters found that under the lure of violent profits, there is huge space for jewellery fraud, and counterfeiting methods are endless. Information from the China Consumers Association shows that the current complaints about jewellery are on the rise, and many “soft†are actually worthless. Experts remind that there are currently about 300 kinds of gemstones in the world, and more than 90% of them have similar gemstones or almost imitations.
Reporter survey:
Jewelry can be counter-offered to a discount
Recently, the reporter saw in the jewellery counters of several large shopping places that the price difference of jewellery was significant, and the discount was huge after some bargaining, and people could not help but doubt its true value. The reporter took a fancy to a Burmese jade bracelet with a price of 3,160 yuan. After some bargaining, he finally made a 30% discount, as long as 948 yuan. For diamonds marked with the same clarity, the price difference between different brands or booths can reach thousands of dollars. In the major hotels and commercial streets, each jade counter is hung with a two-fold, one-fold billboard.
jeweler:
Jewelry fraud is very common
A businessman who has been engaged in jewelry wholesale business for many years told reporters that behind the arbitrariness of jewelry pricing is the universality of fraudulent behavior. Experts from the National Jewelry Quality Supervision and Inspection Center told reporters that unless they are experienced gemstone experts, it is difficult for ordinary consumers to see the difference between “natural†and “artificial†by the naked eye. At present, the market is full of a large number of highly imitation imitation pearls, dyed pearls, and high-grade jade and diamonds impersonated with cheap jade and artificial gemstones, as well as a variety of fake gemstones, such as glass products and mosaic stones. .
A city's industrial and commercial bureau recently conducted quality monitoring on gold jewellery in circulation. The monitoring involved a total of 248 items of precious metals (including gold, platinum and silver), diamonds, gemstones, etc., and the passing rate of testing was only 79.4%. The monitoring situation found that the gold jewellery commodity market in the circulation field showed the phenomenon of “two highs and two lowsâ€: First, the qualification rate of precious metals was higher, and the qualification rate of diamonds and gemstones was lower. Second, the franchise store has a high pass rate, and the “shop-in-shop†opened in supermarkets and hypermarkets has a low pass rate. Only one of the 7 supermarkets and hypermarkets monitored was fully qualified.
It is understood that the main problems in the detection of unqualified jewellery are: First, false markings, such as marking 0.492 carats of diamonds into 0.50 carats. The second is to fake the truth and to infer the quality. Individual merchants label plastic products as amber jewelry, glass products as crystals, glass cat eye products as opal stones, and hand-treated gemstones as natural gemstones, so that their prices suddenly increase. Third, the logo is not standardized. In the monitoring, it was found that the jade jewelry was not marked according to the national standard requirements. The most typical one was to simply label the “synthetic cubic zirconia†jewelry as “zircon†jewelry. "Zircon" is a natural gemstone, while "synthetic cubic zirconia" is synthetic.
Quality inspection engineer:
Some fake diamonds can fool the instrument
An engineer from a provincial gold jewellery and jade product quality supervision and inspection center told reporters that there are currently more than 300 kinds of gemstones in the world. Almost every gemstone has similar gems or almost imitations. In the previous classification of more than 160 pieces of diamonds, more than 140 pieces were found to be silicon carbide. The two are almost indistinguishable from diamonds, but the price is tens of thousands of times different.
Experts also revealed that the identification of fake diamonds, sometimes the instrument can not do anything. The thermal conductivity of a diamond is the best in a gemstone, so a thermal conductivity meter is called a specialized instrument for identifying diamonds. However, coated diamonds produced by a combination of high pressure and chemical vapor deposition were measured by a thermal conductivity meter and found to have a similar reaction to natural diamonds.
Wang Qianhu, director of the Consumer Guidance Department of the China Consumers Association, said in an interview with this reporter yesterday that the current complaints about jewellery and jade are on the rise, with most of the tourist attractions.
