Collecting 10 years of "Old Pit Jade" is actually chemical processing
In the first half of this year, more than a thousand consumers came to test gold and silver jewellery, and the number of inspections increased by about 20% over the same period last year. According to Fang Damin, director of the Gold and Silver Jewelry Inspection Department of the Harbin Quality Inspection Institute, nearly 30% of the jewelry submitted for inspection has problems, and nearly 80% of the jewelry items are from tourist attractions and jewelry exhibitions. Sending inspection jewelry: "Hetian jade" pendant purchase price: 5000 yuan Identification result: glass products Ms. Li of Harbin City traveled to other places last year. When she visited the antique market, she saw a “Hetian jade and white jade pendant†with a price of 8,600 yuan. She would never move again if she loved jade jewelry. After some bargaining, Ms. Li finally used the 5,000 yuan to put this pendant in her pocket. After that, she wore it on her neck every day and played it from time to time. In March of this year, Ms. Li found that there was no change in the pendant for nearly one year. When asking a friend who knows how to do it, the other party suspected that it was a fake. It is recommended that she should make an identification. This test found that the pendant was actually made of glass.

Many imitations can be faked, and only experts can distinguish them." Fang Damin said that some folks are watching colors, listening to sounds, etc. The identification method is only suitable for a few experienced experts. It is best for ordinary consumers to purchase at a regular jade shop. In April of this year, Mr. Sun and his family traveled abroad and purchased two “amber†pendants for 9600 yuan. After the return of the tour, Mr. Sun took the "Amber" pendant and showed off with his friends. He repeatedly said that "foreign sales are cheap, and they have reached the treasure." After seeing a friend, I feel that there may be a problem with amber. I suggest that he go to the identification. Although his friend said that his friend had looked away, Mr. Sun sent the amber to the test, but the result surprised him. Both pendants were all plastic products. Expert reminder: beware of three "high imitation amber" "A year-to-date, amber has become a new hot spot for citizens to check. After testing, nearly 50% of them are fake." According to Fang Damin, the current amber imitation products are mainly divided into three types: 1. Plastic imitation amber; Resin imitation of amber; 3, reconstituted amber: will be made of amber debris plus some special chemicals. Among the three imitations, only plastic imitations can be easily distinguished by methods such as “dipping brineâ€, while the other two types of simulation are extremely high, and only relying on professional instruments can be distinguished. Purchase price: nearly 10,000 yuan identification results: made by chemical processing Ten years ago, Ms. Chen of Harbin spent nearly 10,000 yuan at the jewelry exhibition to buy an "old pit filled with green jade fingers", when the merchants said that it was natural jade, absolutely fidelity. Ms. Chen saw that the water was good, and she was full of green. She bought it for 9,200 yuan. She wore it almost every day for ten years, and she couldn’t put it down. In May of this year, Ms. Chen borrowed a finger from her and accidentally dropped her finger on the floor and cracked. Because of the compensation involved, Ms. Chen sent the finger to the test, but the test result was “Jade (handling)â€, which means that the finger is not pure natural jade, it is a B-car jade that has been artificially processed by man. Experts suggest: Jade is "too clean" to be careful about the introduction of the house, A cargo is a natural jade processed by physical engraving; B goods are treated by acid soaking, injection molding and other artificial chemical methods, removing the impurities in the jade, so that the original The extremely poor jade became clean and transparent. C goods are the worst grade, this jade has no color itself, and it can be changed in color after chemical treatment. Natural jadeite is hard to be "perfect", so jade that is too "clean" is probably chemically treated.
