Recently, jewelry fraud has attracted people’s attention again. Foreign tests have found that some people pretend synthetic diamonds to be natural diamonds. For example, some small synthetic diamonds are used as “secondary stones” of “fully-inlaid” diamond jewelry, making it difficult for consumers to distinguish between true and false, this phenomenon has attracted great attention from the industry. & shy; Not long ago, the jewelry inspection center of Guangdong Geological Research Institute detected a beautiful diamond ring. Its 12 decorative diamond in the debris “auxiliary stones” around large-sized main diamonds, each weighing between 0.09 and 0.12 karat, tested by instruments, confirm that 3 of the “secondary stones” are synthetic diamonds. According to the market price, this makes consumers lose more than 5,000 yuan. & shy; In this regard, Fuzhou jewelry experts believe that most consumers only pay attention to the authenticity and quality of large-sized main stones of diamond ornament, and seldom pay attention to small particle diamond distribution, therefore, it provides illegal merchants with the opportunity of “mix the fictitious with the genuine. At present, there are methods such as “high temperature and high pressure” and “chemical vapor deposition” in the market to make synthetic diamonds. However, synthetic diamonds are not different from natural diamonds in appearance and 4C standard, so it is difficult to distinguish them with naked eyes. & shy; Rong local jewelry experts suggest that consumers must choose big brands or regular gold stores to buy diamond decorations, and try not to buy big carat diamonds online. If you want to purchase online, we also recommend that you check the information on the website of the relevant authentication certificate. In addition, consumers should try not to buy low-priced diamond jewelry products with incomplete certificates. (Reporter Li Yonghua)
