1; I just put jade on my face and felt very cold. If it doesn't get cold for two or three seconds, it means it's true. Because jadeite can transfer heat and dissipate heat quickly! If it is not cold on the face, it is fake. 2; That is, the magnifying glass should be 10 or 30 times to look at the crystals inside to see if there are any small cracks like cobwebs, and whether the color is on the cracks or on the jade surface. If there is, it is fake. Hetian jade looks like rice paste, because the crystal is fine and the color is even. Jade looks like the wings of a fly, some like a little ofloxacin, and some like broken glass. Because the jadeite crystal is not delicate enough, there are many colors on the same jadeite. 3; It's an appraisal of destruction. Set it on fire. It's just burnt black, burnt yellow and stinky. Black and yellow are fake if they are not washed off. It's burnt and smelly. That's even more fake. Really, when the fire comes, there will be small water droplets attached to the jade surface, which will burn black and return to its original color after washing. But we generally don't use this method, which is not good for jade. With the improvement of people's living standards, jade pendants worn by princes and nobles in the past gradually entered the homes of ordinary people. So, how to appreciate the jade pendant? First, look at the material: the material is the primary prerequisite for appreciating the jade pendant. High-quality jade is very important for a jade pendant. Jade quality, jade color, luster, density, cracking and dyeing are all elements of jade grade, which can not be ignored. Second, identify the shape: shape is the aesthetic framework of jade pendant, and it is also an important factor to determine the value of jade pendant. Modeling is determined by the function and shape of jade blank, and its proportion should be properly weighed. Symmetrical but not rigid, balanced and stable jade pendant is a beautiful work. Third, the pattern: the pattern is the decoration of the jade pendant, and its beauty and ugliness are easy to be perceived and felt. Generally speaking, it is subject to the needs of decline, or both depend on the needs of social functions. Decorations depend on structure, composition, complexity and density, and any orderly, unified and harmonious structure has appreciation value. Fourth, technical analysis: technology is the technical condition for changing from material to falling, its nature is relatively stable, and it is not easy to be truly recognized, which is a difficult problem in appreciation. Every neat, smooth and meticulous thallium worker must be beautiful or relatively beautiful. On the contrary, dull and delicate, slow-moving, is a sign of a sharp decline in collection value, and it is not appropriate to collect it rashly. V. Art: Art is the highest realm pursued by every jade pendant, and it is also the most difficult to achieve. Everything with vivid charm and both form and spirit is the expression of artistic beauty, which embodies rich collection value. On the contrary, those who are ruined and blindly extend the ancient people are works that violate the artistic beauty, and their appreciation value is much inferior. Sixth, concept innovation: From the perspective of artistic innovation, the innovative jade pendant can better show the unique personality. Seven, inlay: jade pendant can be plain, can also be inlaid, can be thick or thin, can be large or small, no matter what shape should be outlined separately, there is a saying that is good and exquisite. Wearing a jade pendant pays attention to beauty. Wearing jade pendant pays attention to aesthetics, which is the expression of cultural taste and aesthetic taste, and is the natural information to convey personality. Paying attention to the beauty of dress is to show your inner world and self-improvement spirit. Stress is an intuitive aesthetic judgment, which is influenced by society, culture, class, region and customs, varies from person to person and constantly changes and develops. People are always innovating and paying attention to new exquisiteness with new exploration. With the continuous deduction of the historical process, different nationalities pay attention to dress, show different styles and schools, and form a colorful dress decoration culture. It is human nature to love, appreciate, appreciate and pursue beauty. While pursuing inner beauty, it is also the most natural desire of modern people to make their appearance, clothing and dressing beautiful and their life beautiful. Jade pendant jewelry is not only a commodity, but also a manifestation of cultural taste and an organic combination of culture and beauty. The beauty of jade pendant jewelry must be properly expressed, that is, only by correctly choosing the jade pendant that suits you can you give others pleasure, confidence and excitement. Therefore, when choosing jade pendant ornaments, we must combine our own situation and our own personality. Generally, it can be roughly divided into three aspects: one is one's own temperament, personality, figure, posture and so on. Secondly, location, environment, time, etc. Dress; The third is their own clothing design style, color, texture and so on. Only on the basis of correct choice of wearing, the aesthetic value of jade pendant will be reflected, and the wearer will be more elegant and beautiful. At this time, the style, color and design style of the jade pendant are all important factors to be considered. Wearing jade pendant is a means of shaping spiritual image, and paying attention to it plays an important role in promoting the finishing touch. Common fake jade includes plastic, stained glass, Kangwa stone, marble, synthetic jade made of jade powder and crystal with salt water, and other different fake methods. Reliable identification methods generally include: inspection method: mainly used to see whether there are cracks in jade, the quality jade without cracks, followed by cracks. Even if it is real jade, the value of cracks is greatly reduced. The more cracks, the more obvious and the lower the value. Ten jade and nine cracks, no one can become a jade. Magnifier observation method: observe the internal structure of jade under a magnifying glass, and the product with uniform color distribution is a. Specific gravity method: real jade feels heavy, while fake jade is light and shiny: whether it is translucent or opaque, real jade has a warm luster, and it is normal to have a small amount of impurities or cotton wool-like patterns inside; Fake jade articles are dry and dull, and some have bubbles. Listen to the voice: hang the jade with a thread and knock it with a hard object. Authentic voice is crisp and pleasant, and the aftertaste is melodious; False is a relatively flat and dry moisture identification method. Drop a drop of water on the jade, if it is dew-like, it will last for a long time. The water drops will soon disappear. If real jade is touched by hand, it will feel cold and lubricated. In view of its authenticity, we can observe it from three aspects: first, because glass is very brittle and hard, its structure is loose, and it lacks the density and toughness of jade, and it can't stand strong high-speed rotary carving. Therefore, it is generally impossible to process high relief and round carving on glass. Second, use a magnifying glass to find bubbles, even if you can only see one, it is glass. Third, chromium oxide is added to the glass, and the color is close to ruby; Adding cobalt oxide, the color is close to sapphire; Adding chromium oxide and copper oxide, the color is close to emerald. There are many colors. However, its color tone is always relatively thin, lacking the oily and rich feeling of natural jade color. The more difficult varieties are mainly fake jade made of polymer materials. Its color can be adjusted at will, and it is difficult to find bubbles under a magnifying glass. It is said that the original appearance can be displayed on the infrared spectrometer, but the key to visual inspection is to see whether there are natural stone lines on the surface of the instrument, in addition to the general unrealistic destructive inspection, cracking to find the stone section, burning to see its reaction. After all, manual processing is unnatural and will be exposed under a magnifying glass. The identification of jadeite can be divided into two categories: new jade and old jade. The identification of new jade focuses on the authenticity of the variety, the quality of the texture and the fineness of the sculptor. Some technical contents have been talked about before. However, the identification of Lao Yu is unusual. In addition to several basic requirements, new jade also needs to know the production age and historical value of jade. The confirmation of the historical value of jade is based on a clear era. Familiar with the common shapes, characteristic crafts and popular colors of jade in different times. Then refer to the papers on the characteristics of jade in a certain era, and get in touch with each other, and your jade dating level will be rationally improved. At this time, you should contact the real thing as much as possible and correct the parallax between the picture and the real thing in the book. In addition, the judgment of the times allows a certain span on some jade articles. Because jade tools are precious and not perishable, as a family heirloom, early jade appeared in tombs hundreds of years later, and there are many precedents. The late period of the last era and the early period of the next era are not completely unified in style. Jade has no date, and subtle differences are normal.
