Jade is the essence of mountains and rivers. Jade culture is the product of the perfect combination of national wisdom and the essence of mountains and rivers. Our ancestors created a glorious and long-lasting jade culture. It can be said that jade is the soul of China, and jade is the treasure of China. The precious and precious of the jade is very valuable. As the jade industry has been unrelenting, the sales of jadeite are very popular. Some unscrupulous merchants often use other jade to pretend to sell jade. Therefore, consumers must polish their eyes when purchasing jadeite, and careful identification can avoid being fooled. Today, let us take a look at the hidden traps in the jade market. 1, shoddy The most common situation in this case is to pretend B goods, C goods, D goods jade as a cargo jade. It is understood that the so-called A-car jade is a pure natural jade product directly polished with jade raw materials without impurities, which is the true jade. The so-called B goods are rinsed with impurities, and the natural jade is immersed in a strong acid and then filled with glue. This way, the impurities inside the jadeite can be removed and the transparency can be improved. However, the aging of the glue will occur over time, so that the surface of the jade will become yellow and dry, and the transparency will decrease. In addition to the rinsing impurities, the C product was also artificially dyed. D goods is a kind of jadeite coated with color film, the material is also natural, but the surface of this layer of colored film will age and fall off. Experts from the National Jewelry Quality Supervision and Testing Center pointed out that the normal jade production is only to cut, polish, and sculpt the jade. These treatment methods are all normal processing methods. Once it has been treated with strong acid, bleached and filled, and dyed, it is not a natural gem, nor does it have the effect of preserving and adding value. It is just an ornament. 2, with fake The most common is the stained quartz stone posing as emerald. Dyed quartz stone is commonly known as Malaysian jade, Malay jade, and Ma jade. Because the color is green, it is a common item of imitation jade. There is also a dyed serpentine jade (岫玉) posing as a "blood jade". It is said that the dye used at the beginning is actually red ink. There is also glass-like white jade (nephrite) and agate. 3, name confusion Some refer to white or yellow marble as white jade and topaz, and green jade is collectively referred to as jade, which is easily mixed with jade. 4, the price trap Some merchants use the psychology of investors who like to "price bargain", mark the sky-high price, and then casually bargain the price of the buyer, and want to cut how much to cut, as long as it is not lower than the cost price. Therefore, most of the time, the merchants complained on the surface, but their hearts were secretly happy. Consumers Association has received a complaint, a customer bought a jade bracelet in a tourist attraction, the price of 25,000 yuan, he spent 2000 yuan to buy, according to experts estimate, the standard price of this material jade bracelet should be less than 1000 yuan.
