The general method of jade identification: good jade is mostly very expensive, so the identification and selection technology is very demanding. Professionals can use scientific instruments to identify, and how should we generally identify jade friends? Experts also summed up some experiences in identifying true and false and judging the pros and cons. The preciousness and rarity of Hetian jade also attracts various businesses, and there are also many people who are mixed with fish. In order to let everyone know about Hetian jade clearly, here are some simple ways to identify Hetian jade. Water identification Drop a drop of water on the jade, such as a dew-like shape, and if it is not scattered for a long time, it is a real jade; on the contrary, the water droplets quickly disappear is a fake. Because the jade texture is tight, it is not easy to absorb water, and the stone is loose in structure and easy to absorb water. Hand touch method: If it is a real jade touched by hand or a try on the cheek, there is a sense of cold lubrication. Inspection method: The jade is turned to the light, such as the light, if the color is transparent and the chromaticity is evenly distributed, it is true jade. Tongue method The tip of the tongue is really jealous; the fake jade is just innocent. Magnifying glass watch: The purchased jadeware is placed under the magnifying glass to watch, mainly to see if there are cracks. Those without cracks are superior quality jade, and those with cracks are the second. Even if it is true jade, the value of cracks is greatly reduced. The more the cracks are more obvious, the lower the value. Quartzite jade, color white, fine texture, looks like white jade, the so-called "Jingbaiyu" in the past, is a fine-grained quartzite, "oil stone" mine evaluated by the geology and mining department, the particles are very fine, but can not be called White jade, quartzite jade hardness is higher than white jade, so it shows a stronger glass luster than white jade, in the absence of instrument testing, can be resolved accordingly. 1. Water stone: The main component of this jade is quartzite, which has high hardness, but is brittle and easy to break. The internal structure is granular. The color is pale and the gloss looks dry. 2. Water white jade: It is a kind of Nanyang jade in Henan. It is plagioclase, glass luster, some are very transparent, and also semi-transparent. The handcuffs are lighter, and the whole looks white and black (with gray or blue and blue) Jade is totally different), but when you look closely, you can't find the place where "Wu" is, also called Wubaiyu, which is more common on the stalls. 3. Dongling jade: more places of origin, Xinjiang also produces Dongling jade, is a quartzite, granular structure, strong gloss, slightly lighter weight, Dongling jade is also commonly used to make jade jewelry, Dongling jade bracelet market price of about 100- About 150 yuan, small pendants about 30-50 yuan, the famous stone records have many Guanyin and Buddha. Several other jade similar to white jade are rarely used for jewelry, because the value is too low, only used to make large carvings. Calcite jade Calcite jade, the appearance of similar white jade, for example, the so-called "Afghanistan white jade" on the market is a jade formed by calcite, in fact, is a kind of marble, but the color is very white, translucent, often carved into cabbage, meaning the symbol of "hundred wealth" . This kind of jade has a very low hardness, and it can be easily recognized by ordinary knives. 1. Marble: This jade color is white, the gloss is waxy, and the internal structure is waterline and stripe. 2. Afghan white jade: Because the white jade of Afghanistan is very fine and uniform, the luster is lustrous, the jade flower is not visible to the naked eye, and it is often used to pretend to be the best white jade or suet jade. The method of identification is very simple, just scrape it with your fingernails. If you can scrape a little white skin, it is not white jade. In addition, there is a kind of serpentine jade, namely jade jade, which is produced in Xiuyan County, Liaoning Province. The jade jade has a large output, low hardness, easy breakage and low price. The general transparency is relatively high, mainly in green, mainly used to pretend to be Tianqing white jade, sapphire, yellow jade is also more common, mainly posing as topaz. Now Xinjiang has also discovered a large number of serpentine jade. Since the hardness of the jade jade is less than 5, the glass can not be moved. Caution trap In particular, it should be pointed out that some used markets often use emulsified glass to impersonate white jade or ancient jade, and circular bubbles of varying sizes are often seen in glass products. As long as you see bubbles, you are definitely not white jade. However, some glass products have no bubbles, so those who do not have bubbles are not necessarily genuine. To be sure to buy the real goods, you should still look for the testing department of jewelry and jade, because some white jade looks like white jade, it is difficult to make accurate judgment without strict testing. Hetian jade has a high hardness and a strong toughness. Hetian jade can cut glass without damage. For other jade, only quartzite jade can be scratched without damage. The water stone is often used to pretend to be the best sheep fat jade in Hetian jade. The sheep fat jade is the white color of the sheep fat, the water stone is the pale color; the sheep fat jade is the grease luster, the water stone is dry and the gloss is not good. Finally, from the appearance of distinguishing Hetian Baiyu has three aspects, Hetian Baiyu can see the fine small cloud-like, cloud-like structure of jade flower, which is the unique structural characteristics of Hetian Baiyu; Hetian Baiyu's luster is very warm, not that It has a strong glass luster, which means that the surface of Hetian Baiyu does not reflect light very much. This is because the surface of Hetian Baiyu has very fine bumps, similar to frosted glass, which can be seen with a magnifying glass 10-20 times. Sometimes you can also see the traces left by hand-grinding in a certain direction; pay attention to observe the inscription line, because Hetian Baiyu has a strong toughness, it is not easy to collapse when carving, and it is not easy to crack on both sides of the Yinxian line, quartz Although the hardness of rock jade is high, the toughness is poor, the brittleness is strong, and the indented line is prone to collapse.
