How to distinguish white jade products
White jade is a jade stone mainly composed of tremolite and soft jade (Hetian jade). Some operators will not be white jade white jade is always called white jade, objectively misleading consumers, deliberately will not be white jade white jade called white jade, to fake the truth, this is illegal behavior. On the Internet, some sellers often deliberately call a white Dongling jade produced in Xinjiang as “Xinjiang white jadeâ€, which is confusing. Many buyers complained after the complaint. The seller also argued that there are many kinds of white jade in Xinjiang. He did not say that it is Hetian. Jade-white jade. In the jade market, there are often two kinds of white jade called white jade. The first is quartzite jade, white in color and fine in texture. The appearance is very similar to white jade. In the past, the so-called "Jingbaiyu" is a kind of fine-grained quartzite, the "oil stone" mine evaluated by the geo-mineral department. The particles are very fine, but they cannot Known as white jade, the jadeite hardness of quartzite is higher than that of Tianbaiyu, so it shows stronger glass luster than white jade. In the absence of instrumental detection, it 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: common Dongling jade is green, also has blue, red, white, and more places of origin. Dongling jade produced in Xinjiang is white, belonging to quartzite, granular structure, strong gloss, slightly lighter weight, east Lingyu is also commonly used to make jade jewelry. The market price of Dongling jade bracelet is about 100-150 yuan, and the small pendant is about 30-50 yuan. The famous stone records have many Guanyin and Buddha of Dongling jade, sometimes green Dongling. Jade is often used to make green jade. Several other jade similar to white jade are rarely used for jewelry, because the value is too low, only used to make large carvings.
The second is calcite jade, the appearance is similar to white jade. For example, the so-called “Afghanistan white jade†on the market is a jade formed by calcite. It is actually a kind of marble, but the color is very white, translucent, often carved into cabbage, meaning “100. fiscal". 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 hardness is low, the gloss is waxy luster, 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. There is also a 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. Generally, the transparency is relatively high. It is mainly composed of lake water and green. It is mainly used to pretend to be Tianqing white jade and sapphire. Yellow jade is also common, mainly posing as topaz, jade jade also has white, and jade has cotton wool. 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. 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.
From the appearance, there are three aspects in the appearance of Hetian Baiyu. Hetian Baiyu can see the fine small cloud-like, cloud-like structure of jade flower, which is the unique structural feature of Hetian Baiyu; Hetian Baiyu's luster is very warm, not the kind. Strong glass luster, that is, the surface of Hetian Baiyu is not very reflective to light. 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 see the traces left in a certain direction by hand polishing; pay attention to the obscured line, because Hetian Baiyu has a strong toughness, it is not easy to collapse when engraving, and it is not easy to crack on both sides of the Yinxian line. Quartzite Although the hardness of jade is high, the toughness is poor, the brittleness is strong, and the intaglio line is prone to collapse. It is for this reason that many quartzite-type jade are pressed out at high temperatures by molds, without traces of hand-carving.
