How to identify the authenticity and quality of jade

Among the virtual simulation software for jewelry and jade identification mentioned at present, the infrared spectrum three-dimensional simulation software could be used for jade identification. It was based on the national standard," Gem and Jade Identification by infrared spectrum method ", which simulated the whole operation process of Thermo Fei Nicolete iS5. It also established a typical infrared spectrum library of gems and jade. Students could identify gems and jade through peak marking, amplification and other functions, including the identification of gem species, the distinction between natural and synthetic gems, and the identification of whether they had been artificially optimized. However, there was no mention of whether there was a generally applicable software that specialized in identifying the authenticity of jade. In actual jade identification, professional tools such as magnifying glasses to observe defective bubbles, infrared lamps to see if there was abnormal fluorescence, and spectrum analyzer were used. At the same time, there were professional official appraisers in the jade app to identify the quality of Hetian jade. Zhuang Jadeite established the GID Jadeite Laboratory to identify the origin of the jade. " Fairy Dream of Tang Shi: Fate of Peony " is equally wonderful. Everyone is welcome to click and read it!

To identify the authenticity of jade articles, one could start from the following aspects: 1. ** Color: The color of real jade is naturally warm and evenly distributed, while the color of fake jade is often too bright and dull. 2. ** Quality **: - The internal structure could be observed with a light. The texture of the real jade stone was natural and smooth, while the fake jade stone might have unnatural features such as bubbles and flaws. - The real jade had a fine texture and a compact structure, while the fake jade that had been pickled had a loose internal structure. 3. In terms of temperature and touch, the real jade felt cool at first, but soon became the same as the body temperature. The fake jade might always be cold or warm. 4. ** In terms of weight **: The internal structure of natural jade is mostly dense and delicate, and there is an obvious feeling of pressure in the hand; the pickled fake jade is heavy and does not feel pressure in the hand. 5. ** Other aspects **: - It could be used to help judge. - Touching it with his hand, the jade of different density felt different. If the density of Hetian jade was higher, it would be heavier. - Using light observation, for example, the staff in the jade shop often used a flashlight to illuminate the jade to assist in identification. - Judging from the sound, it was clear and crisp. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In the reference materials, it was mentioned that Brother Yi had 33 years of practical experience in the jewelry industry. He could identify jadeite, Tian jade, and other jewelry and jade. Moreover, he was livestreaming the appraisal on TikTok. However, at present, he could only find this streamer who verified the authenticity of the jade. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The method to distinguish the authenticity of Hetian jade is as follows: 1. [Observing internal structure: Natural Hetian jade has a fine texture, oily luster, moderate hardness, and unique contents and patterns.] It could be observed with a magnifying glass or professional optical instrument. The internal structure of the real Hetian jade was fine and uniform, and the crystal boundary was blurry. The fake internal structure was rough and there might be traces of processing. 2. ** Check the certificate of origin **: Hetian jade has a specific origin. The authentic one is Hetian, Xinjiang. The certificate of origin contained the jade's composition, hardness, density, and other test data, which could be used as a basis for judgment. 3. ** Feel the weight and touch **: Real Hetian jade feels warm and heavy. Because of its high density, it is heavier than fake jade in the same volume. Fake jade may feel too light or lack warmth. 4. ** Carry out optical identification **: In addition to observing the internal structure with a magnifying glass, it can also be judged according to the reflection characteristics. Real Hetian jade has a greasy luster, while fake jade may have a glass luster or other unnatural luster. 5. ** Detection of density **: immerse the Hetian jade completely in water and divide the first weight by the second weight to obtain the density. This will help to determine whether it is real or fake. 6. ** Feel the temperature of the hand **: The real Hetian jade feels cold when touched by the hand, and the fake feels gentle after touching. 7. ** Listen to the sound of knocking **: Natural Hetian jade will make a clear sound after being knocked, while fake Hetian jade will make a dull sound. 8. ** Light up and observe **: - ** Direct light **: Use a flashlight to direct the surface of the jade. The real Hetian jade has a relatively high light transmission, and the light from the imitation jade is relatively scattered. - ** Backlight **: The flashlight shines from the back of the jade to observe the impurities or cracks. - Oblique Light: Oblique Light can observe the structure of Hetian jade. Natural Hetian jade is densely distributed. Man-made Hetian jade does not have such a structure. The method to judge the quality of Hetian jade was as follows: 1. ** Look at the pores **: observe the thickness and distribution of the pores on the surface of Hetian jade. The pores are small and densely distributed, indicating that the meat quality is good. On the contrary, the jade quality is ordinary. 2. ** Look at the light transmission **: The finer the texture of Hetian jade, the worse the light transmission. Semi-transparent or slightly transparent means that the jade is tight. If the light transmission is good or even completely transparent, the jade is loose and the quality is not high. 3. ** Depends on the degree of oiliness **: Good Hetian jade has a greasy feeling. The jade is fine and tight, so the greasy feeling is strong, the degree of oiliness is high, and the quality is good. The jade is loose, so the greasy feeling is poor, and the quality is poor. 4. ** Skin color (targeted at seeds)**: The formation of skin color is related to the infiltration of mineral ions in the water. Generally, the darker the skin color, the rougher the jade quality. However, it also depended on the depth of the skin color. A light skin color could not explain the condition of the entire piece of jade. 5. ** Look at the seep color **: The seep color is similar to the skin color, but it goes deeper inside. When the color was deep, the jade was loose, but it was rare to see a whole piece of jade being soaked in sugar, so it was considered a good quality jade. In addition, the safest way was to send Hetian jade to a qualified professional testing agency for identification. The novel "Ledge" is equally exciting. Everyone is welcome to click and read it!

To identify the authenticity of jade, one could start from the following aspects: ** 1. Color ** 1. ** Natural jade color characteristics ** - The color of natural jade was naturally formed. The color was natural and evenly distributed. For example, Hetian jade, a high-quality white should be warm and shiny, not a dazzling cold white, but a soft white with a "fat feeling." If a piece of jade was as white as a piece of paper, it might be a "fake white jade" that had been treated with whiteness. - For jade and other jades, if the color was too thick, stiff, and not as natural as the color of natural jade, it might have been processed or forged. 2. ** Fake Jade Color Specialties ** - Fake jade was dry, dull, and lifeless. It was like jade that was made of glass. Its color was often too transparent and perfect, and it did not have the natural feeling of natural jade. ** 2. Hand feeling ** 1. ** True Jade Touch ** - True jade had a certain density, and holding it in his hand would give him a corresponding feeling. For example, Hetian jade had a high density. When held in one's hand, it would have a heavy feeling, and it would have a slight cool touch. It would have a cold and warm feeling. 2. ** Fake Jade Touch ** - Fake jade might seem light when held, like a glass imitation of jade. It felt rough and almost did not have the cold feeling of real jade. ** 3. In terms of structure ** 1. ** Observing the structure of the real jade with light ** - For Hetian jade, you can use a small flashlight or a mobile phone flashlight to observe the jade. There was a fiber interwoven structure inside the real Hetian jade, like layers of fat fibers. - Different jades had their own unique natural structure when observed by light. For example, if the jade was processed by acid corrosion (B grade jade), some grid-like patterns that were not found in natural jade might be seen in the structure. 2. ** Fake Jade's structural characteristics ** - Inferior fake jade was either too transparent or the fiber structure could not be seen at all (for jade with fiber structure characteristics like Hetian jade). ** 4. Sound ** 1. ** True Jade's Voice Attribute ** - Good Hetian jade would produce a crisp echo when struck, especially the best seed material. When struck, one could hear a long and deep tone. As for the other jade pieces, they were hung up with thin threads and knocked lightly with a hard object. The sound of the real jade was crisp and pleasant, and the aftertaste was melodious. 2. ** Fake Jade's voice characteristics ** - The low-quality fake jade was mostly a dull "plastic sound" or a metal-like "hard sound". ** 5. Other special identification methods ** 1. ** Hetian Jade's Water Drop Test ** - The surface of Hetian jade was extremely dense and smooth. If a drop of water was dropped on its surface, the water drop would remain round and not spread easily. If it was a fake jade, the water droplets would disperse very quickly. 2. ** For the pore identification of Hetian Jade Seed Material (For Hetian Jade Seed Material)** - ** Pore shape and size **: The pores of the natural seed material are traces left by running water. They are small on the outside and large on the inside. They have a certain depth and are shaped like the pores on human skin. They are delicate and smooth to the touch. The pores of the sandblasted seed were large on the outside and small on the inside, showing the shape of an open trumpet. In the beginning, the pores of the sandblasted seed were rough and shallow, but after improvement, they were too small. - ** Direction and angle of erosion marks **: Natural seeds are formed by being washed in the river for a long time. The erosion angle of each position will change according to the shape of the original stone, and it looks smooth and natural. The sandblasting machine carried out a flat impact, and the angles of the pores were often the same. Even if the shape of the jade stone changed at the corner, the sandblasting marks remained the same, which seemed unnatural. - ** The relationship between the degree of pore exquisiteness and jade quality **: The finer the jade quality of Hetian seed material, the finer the pores. The pores of different parts of the natural seed material have significant differences. Even if the quality of the jade stone was poor, the pores might be processed to be extremely fine. The appearance of overly well-proportioned pores on the raw materials should be vigilant. - [Over-naturalness: The pores of the natural seed material are naturally formed in the water. The changes are smooth and natural. There are no traces of deliberate creation.] Although the sandblasting imitation seeds could be adjusted, the changes were step-by-step, and the details were often abrupt. - ** The relationship between the skin color and the pores: The skin color of the natural seed material and the pores are produced simultaneously, and it is difficult to distinguish the order. The surface skin color and the pores are integrated into one. Sandblasting imitation seeds were first sandblasted and then dyed. The skin color often floated above the pores, and sometimes there would be deposits in the potholes. 3. ** Hardness test (applicable to some jade)** - When the jade was slid across the glass, the glass would leave obvious scratches, but the jade itself would not leave any marks. However, this method was not suitable for all jade, and it might cause some damage to the jade, so it needed to be used with caution. The novel "Dream of Silk Fate" is equally exciting.

The authenticity of a whole box of Moutai liquor could be verified by the following methods: 1. Look at the seal: The original Moutai seal had a wide seam, with obvious signs of compression. The end of the seal was serrated and neat. The seal of the fake wine might not have any signs of compression, or the marks might be very shallow, and the workmanship of the seal would be relatively poor. 2. Looking at the printing, the serial number or date of the genuine Moutai wine was printed by the ink jet printer, and there was a line in the middle of the numbers. The number of the fake Moutai liquor was artificially added, so there would not be this line. 3. Look at the logo: There are three labels on the front of the genuine Moutai packaging. If it is missing, it is suspected of being fake. The labels of the real wine were clear, the color was uniform, and the workmanship was careful, while the labels of the fake wine might be rough and simple. In addition, one could also identify the Moutai by observing the logo at the bottom of the bottle, the Moutai logo on the bottle cap, the color of the packing tape of the whole box of wine, and the spray code of the Moutai. Please note that the above methods are only for reference. If you need a more accurate identification, please consult a professional or official channel.
