Jade and jade psychic teasing, in the classical culture also occupy a permanent place. However, jadeite is a kind of exquisite jade. Many people use other jade to pretend to be jade. It is not that jade is not good, but it is bought at the price of jade, that is, taking medicine. In general, there are several kinds of jade that can be chaotically jade on the outside, but in fact, as long as you carefully observe a lot of learning, the difference between them and jade can be seen with the naked eye.
The most common jade "pretender"
"Qinghai Cui"
The real name is water calcium aluminum garnet, a polycrystalline aggregate of calcium aluminum garnet in the garnet family. Strictly speaking, it is not just a collection of minerals. The color is green and green, very similar to the green jadeite. The “Qinghai Cui†with better transparency is more similar to the jadeite with good head. It is not uncommon to use it as a jadeite in the market. Even in many jade shops with large stores and good reputation, they can be deceived and prevented from being prevented. Bad merchants give it "Qinghai Cui", which sounds like jade, using this method to pretend to be a jade fan.
Visual identification: the appearance of gloss is very poor, the best can only achieve a waxy luster translucent state, but also very similar to bean jade. The biggest method of identification is that there is often black chromite in the calcium-calcium aluminum garnet. There are many black spots on the surface. If you think that the surface is too dark and too much abnormal jade, it is best to see if the certificate is true and Carry out a re-examination.
Malay jade
Commonly known as "dyed quartzite", the name of Malay jade is mainly for pretending to be jade, but the essence is just ordinary quartz that cannot reach the gem grade. It is formed by adding dyeing agent after hot melt, and the most common artificial jade counterfeit goods. one.
Visual identification: The strong light bulb shines into the interior from the side and can see a very coarse grain structure. If the color is too uniform and bright green and the glare sees the structure is very thick, and there is no credible jade certificate and the price is unreasonable, it is necessary to take a long-term view and go to the professional appraisal agency for re-examination.
Ice
Straightforward is the stained glass, glass, and feeder. Because the glass is very clean and transparent, it does not affect the transparency after dyeing, so it will pretend to be a good jade. However, this kind of counterfeit goods is relatively low-end, mainly to lay down the layman who does not understand at all. Therefore, it is often seen in the small pavilions of tourist attractions and the low-end jade market. Nowadays, the business name of "Bing Cui" is often the best jade.
Visual identification: Because of the relationship between dyeing, glass needs flame fusion and remodeling, often accompanied by air bubbles; or some plastics are not plastically reshaped during remodeling, there may be uneven ribbon generation, or green dye powder that is not fully integrated. Assembly. Generally, you can see it with a ten-fold magnifying glass.
Dyed agate
Most of the natural agate color has flaws, or the color is not pure and contains a lot of variegated colors, otherwise the color is not bright enough to be grayish green and dark green. Therefore, artificial dyeing is required to make the color look greener and more like jade.
Visual identification: Ordinary agate has a lot of parallel lines, which look like a circle, and the jade's uneven internal cotton structure is different. And the green and white parts of the dyed goods are too distinct and unnatural. Natural agate is obviously lighter than ordinary jade.
Australian jade
Also known as "Nanyang Jade", it is a kind of green and green Chinese chalcedony, which is a kind of serpentine. Although it is called chalcedony, its transparency is also worse than that of general chalcedony, and the chalcedony is completely different from the silica mineral, which is different from the pyroxene-based polycrystalline aggregate jade. Too false and tender green is the main feature of inducing general layman.
Visual identification: The green color is too fresh and even, and the color floats on the surface of the stone, which is very unsinking, unlike the green from the inside to the surface.
The easiest way to identify jade
Look at color
The color is beautiful is the first element. The most desirable color is bright green (green), although the top color is dark green, but the green is too deep, and people feel too dull, so the top green is instead The price is not as high as the bright green.
See transparency
The high level of transparency has a great influence on the value of jade. The transparent jade gives people a cool feeling, but the opaque jade, the color is more green, but it gives people a feeling of dullness and lack of vivid beauty.
Look at the form
The price of jade is not weighted like other gemstones. Jade is mainly valued by its size and thickness. The bigger the thicker, the more valuable it is. On the contrary, the price of small and thin jade will be worse.
Listen to the sound
This is a special method for selecting jade bracelets. If the jade is good, the sound is crisp. If the jade itself is flawed, if there is crack, hollow or partial deterioration inside, the sound will be different when it is knocked. The feeling is like knocking in the smash, the sound becomes " The voice of Titicaca.
Photo
Take the jade and look at the light, you can see the color and enamel of the jade, and sometimes the jade looks perfect without a flaw.
Look at the price
This is a very simple method of identification. As the saying goes, "a penny is a piece of goods." This is especially true in the jewelry line. There is absolutely no cheap to buy good goods. Usually, bargains are mostly fakes, so we are When buying and selling, it can be inferred from the price level that good jade cannot sell low prices.
