Is there someone who understands to help you look at the value and authenticity? Thank you

Some ways to identify the authenticity of jade. 1. Water drop method; The water is dropped on the jade, if it is a real jade, it will be in the shape of a dew drop and will not spread for a long time, if it is a fake jade, it will flow down in a stream. Second, the hand feel method; Holding the jade for a while, those who have a feeling of cold lubrication are real jade, and those who do not have a feeling of cold lubrication are fake jade.

3. Tongue licking method; If it is real jade, lick the surface with the tip of the tongue, there will be an astringent feeling, if it is fake jade, there is no such feeling. 4. Observational method; If you look at the real jade under a magnifying glass, you can see the traces of artificial carving. Fifth, look at the hardness; The hardness of jade is large, and the real jade can leave scratches on the glass, and the jade is not damaged.

6. Smell the sound; If it's real jade, tapping it lightly will make a crisp sound, and if it's fake jade, it will make a dull sound. 7. Fire method; If it is real jade, wrap a hair strand around the jade, and then use fire to burn the place where the hair touches the jade, and the hair is continuous. 8. Sense of weight; If it is real jade, it feels weighty and heavy in your hand; Fake jade is heavy and fluttering.

9. Look at the color; True jade is exposed to the sun**, and its color is clear and evenly distributed. **: National Cultural Artwork Network 10. Look at impurities; True jade contains various impurities such as small flakes, fine particles, and fibers.

The silver coin is fake, the copper coin is real, and the product difference is **Wu Yuan.

1.The most direct way: mobile phone authenticity.

Moutai took the lead in using RFID technology promoted by the Ministry of Commerce, that is, radio frequency identification technology. This means that the label of each bottle of Moutai product name, specification, production batch, production date, sales channel and other information is equipped with RFID technology chips. Now smartphones are very popular, as long as your mobile phone has NFC function, then you can query Moutai.

Remember: the mobile phone must have NFC function, and Moutai must be manufactured after the use of RFID technology.

2.Keep an eye on the manufacturer.

Moutai is produced by Kweichow Moutai Distillery (Group) Co., Ltd. in China. If it is not named after this name, then it can be judged that it is fake, if there is a note of such and such a branch, such and such a factory, or such and such a factory, joint venture, etc.

3.Carton packing.

There are three trademarks on the packaging box of Moutai's carton. So when buying, be sure to check the trademark carefully and never be sloppy.

4.The wine bottle looks at the clues.

The bottle of Moutai is also very special, and the bottom of a real Moutai bottle will have the registered trademark of Moutai Company, which is the icon of the five-pointed star wheat ear. At the same time, there is a bottle at the bottom of the bottle which factory produced the **. At present, there are 4 types of bottles of Moutai, HB, MB, CKK, and small square (a small rectangle icon).

Of course, the logo on the bottom of the same case of Moutai is the same.

Of course, when you touch the bottle, you will feel that it is very even, and the glass has no impurities.

5.Packaging of wine bottles.

The bottle packaging of Moutai is also very particular. For example, the color on the wine box is bright and uniform, the luster is very good, the pattern on the show is very clear, the trademark is very clear, and the material of the box is also good, but pay attention to the fact that the pattern on it feels concave and convex.

In fact, the packaging technology is already very mature, so it is generally difficult to distinguish. If the seller works the packaging, it will not be lifting a stone to shoot himself in the foot.

6.Application of anti-counterfeiting labels.

When manufacturing Moutai, it is also taken into account that some merchants or individuals will make fake Moutai. Therefore, when designing the cap, the plastic cap with the anti-counterfeiting design will be destroyed after opening the bottle. Of course, those who have seen plastic hats may not necessarily know that under different lighting conditions, especially under the conditions of forward light and backlight, the difference between plastic caps is obvious.

But what should be paid attention to is that there are Chinese characters and pinyin characters of Moutai on the plastic cap, and there can be no light, the two characters of Moutai are very clear, the changes are very small, and there will not be too strong a sense of contrast.

7.Taste it and know if it's real or fake.

People who judge the authenticity of Moutai through this method must have also drunk Moutai and have a certain cognitive foundation. However, in reality, there is a strange phenomenon that "people who buy Moutai do not drink Moutai, and those who drink Moutai do not buy Moutai". So, for many consumers, this trick doesn't seem to be too cold.

Here you have to be verbose about what to pay attention to when tasting Moutai. After all, Moutai is full of color and flavor, so we should pay attention to the color of Moutai when tasting, smell its aroma, and feel its aftertaste and aftertaste.

1 yuan, that seems to be a fake.

The name of this utensil is blue and white dragon pattern pen wash.

The firing age is the nineties of the twentieth century.

Except for a Qianlong style at the bottom, this brush wash does not have the characteristics of the Qianlong era.

From the style point of view, the sole foot is tightened, which is the characteristic of modern pen washing; Looking at the ornamentation, the internal dragon pattern is the unique decoration of Jingdezhen traditional porcelain in the nineties of the last century, and the external decoration is also a modern decoration; Look at the glaze color and material color, which is modern glaze and chemical material color.

Since the revival of the collecting craze in the mid-80s of the last century, the retro style has formed a trend among some of the more sophisticated groups. For this reason, starting from Jingdezhen, ceramic production enterprises around the country fired a lot of porcelain with a retro style, which was very popular at that time.

This brush wash is one of the traditional vintage porcelain fired at that time. Because it does not imitate the shapes and craftsmanship of any period, it is not a fake.

This pen wash is only a practical ceramic product with traditional style, which only has use value and does not have collection value.

Omega watches generally can't distinguish the authenticity from **.

Omega watches can generally be identified from several aspects, such as the case, handle, movement, and laser anti-counterfeiting logo.

First, look at the production serial number.

Omega watches all have a serial number, and they are the only one in the world. It is usually engraved on the back cover of the watch, or on the back of one of the claws of the watch, which is a string of 8-digit numerals. In the case of a mechanical watch, the 8-digit serial number will also appear on the edge of the movement bridge, and the serial number of the case will be the same as that of the movement.

Second, look at the case.

There are many markings on the case, especially for gold watches, such as the pattern of the scale, the mark of 18K or 750, the dog head of St. Bona, or the mark of the woman's head of the "Protector Goddess", which are stamped very small and clear, and the fake watches are often thick and large and blurred. This is because the counterfeiter's mold is cheap and the level of craftsmanship is low, which is of course incomparable with the expensive mold of the original table!

3. Look at the strap.

If it is a metal strap, some logos will be engraved at the discount of the strap, and there must be a strap number, and the logos of fake watches are generally larger, shallower and rougher, because the process requirements are higher, and counterfeit watches are often "powerless" here. If it is a watch in K gold, the buckle of the strap must also be K gold, and it must also be engraved with those logos of K gold, and if it is not gold-plated, then at least it is not the original strap.

Fourth, look at the pointer.

The weakness of counterfeit watches is in the hands, don't look small, but it's not easy to do a lot like it. The surface of the hands of a genuine OMEGA watch is very bright and flat, with a regular and slender shape (especially the seconds hand), and the luminescence on the hand is the same color as the dial. If you can make a comparison, it is not difficult to see the difference.

Fifth, look at the characters and lacquer prints.

The characters of the dial should also be unconventional and shiny on the surface, if it is a diamond word, first of all it should be a natural diamond, while fake watches generally use "rhinestones", and they are larger than the real watch. The lacquer marks on the dial, including the letters and the partings, should be very clear and shiny, and the fake watch is darker and more blurry. swiss

The word made should be at the bottom of the dial at 6 o'clock, close to the aperture of the glass, and the letters of the fake watch are printed relatively high.

Sixth, look at the guarantee card.

Omega watches usually have 2-4 guarantee cards (depending on the model of the watch), all of which are dark red and the same size as a credit card. The number of the watch (model number, serial number, movement number and the blue seal of the seller) is printed on it, which corresponds to the watch. Guarantee the contents of the card:

Includes an international guarantee, a chronometer certificate, a natural diamond guarantee and a guarantee for the functionality of the watch. Fake watches often have numbers that do not correspond, functions do not correspond and there is no seller's blue seal.

The above is the common knowledge of Omega to identify authenticity, although you understand these principles, if you want to ensure the authenticity of the watch, it is best to go to a professional place to identify.
