The past century, high-quality jade is expensive, if the block to 100 grams of glass to Brilliant Green were, per gram price of 1.5 yuan, and there are no goods price trend. Therefore, the driver of the speculative fraud, preventing the consumers only to merchants when buying Jade's side of the story as true, completely lost the initiative should be. So, ready to buy and buyers are rational and have been asked: how to identify Jade A, B, C? A cargo freighter C jade is also called the jade, gem industry has a different argument. Consumers generally considered: Jade's A, B, C, is the jade rank. A as a product, B for the two products, C for the three products. Wrong too! A, B goods, plastic utensils for the man synonymous with bleach injection is not the second best natural jade material. B goods, is the color of the worst natural jadeite jade objects immersed into concentrated hydrochloric acid, the body absorb minerals loss out of non-ferrous metals, to bleaching treatment purposes. Been acid washed jade structure is destroyed because of loose powder slag off easily, or directly fall apart, then used high-pressure plastic injection method, due to coagulation. 2, C goods, artificial coloring jade is not jade the third class of natural products. C goods, is a natural colorless or pale jade color line for high-temperature heat treatment to make it burst, hot soak into the colored chemicals, burst into the color gap in order to achieve dyed purpose. B + C goods, is the artificial acid, gluing, coloring, three kinds of manual processing integrated short, its life is shorter compared B goods. A cargo, goods against B C goods for the purposes of a synonym for natural jade is not jade of a product. A common market to the goods of jade, were the worst color in low-grade products, not by a collection of products at high prices. Clear goods B C goods, does not mean the A store sells goods are genuine, there is need to identify some common sense to grasp. 1, hydrophilic different. A cargo in a drop of surface water (natural fall of water drops), drops the higher processes, will not immediately disperse. B, B + C goods contrary. 2, the surface of different. A cargo jade flat smooth surface, like glass. B, B + C goods as plastic injection causes, feel like plastic, welcome light, the surface uneven, like orange peel. 3, gloss different. A shipment of glass for the oil sheen, like glass, B, B + C goods to waxy luster; C cargo for the weak glass gloss, hair spray. 4, different color. Common to the A store goods, different levels of color are basically glaucum, gray, not bright, not bright. B, B + C goods, non-gray color, were bright green and white are flawless. Mostly white background and green stripes. 5, the color of different shapes. A cargo of the color is uneven, even beans large clumps of color, there are shades of the points, and the colors are visible clumps around the radial slightest form, color line. C, B + C showed a linear distribution of the color of goods, no goods clumps A body, color, no shades of distinction. A cargo dig the money, but bought a B, C or B + C goods, if not written clearly on the invoice payment, according to the law are difficult to prosecute. Well, the stone, glass, plastic jade goods bought as A, is what should the feel? Jade, not a penny or two cents lower-end consumer goods, can afford is the blessing. However, the longer the money is not buying today, tomorrow, throw the garbage. So, we want to buy genuine, but also have to know a little knowledge of jade.
