I ca n’t see it, I ca n’t go in. I will give you the method of identification and some differences. Take a look at it yourself:
. Generally speaking, the jade appraisal refers to Instrument testing and manual identification are two aspects. Instrument testing, it is usually tested by polarizer to test its structural crystal, and the refractive index is tested by the refractor. Test its color elements by filtering the color filter, measure its density through density, obtain its hardness through the hardness meter, test the color spectrum through the spectrocytomometer, etc. The instrument test is highly scientific. It can pass modern science and technology through modern science and technology. The means of testing on a reliable basis are undoubtedly great correctness. Generally, only professional workers have mastered. For most emerald enthusiasts, it is necessary to identify the traditional means of manual identification. The process of manual identification is a process of accumulation, which requires long -term practical experience to accumulate. Generally speaking, you need to start with the following characteristics of emerald: 1. Structure: The structure of the emerald is a spots crystal interwoven structure, which refers to the small fiber -shaped minerals around the transparent granular spots under the deterioration of the quality. The structure formed by the crystal interweave. In the emerald, there are small white flowers composed of opaque or slightly transparent white fiber crystals, so it is called "stone flower" or "stone brain". 2. Puts: Emerald's pits are composed of structure and texture, and emeralds are composed of small crystals. The smaller the crystals, the more dense the texture, the better the transparency, and the effect of the polishing effect. The better. In the jewelry industry, the pits are divided into old pits (also known as old species) and new pit (also known as new species). The old pit is bright and moist, and the color and earth are integrated into one. The new pit, although the color is also tender, but the transparency is poor. Laokeng and Xinkeng are determined based on how much the emerald formation. 3. Color: The difference between the color level of the jadeite is very related in value. When identifying the emerald, it must distinguish it. Green, strong purple, and red are high -end colors in emerald, especially green as the most expensive. The green of emerald should be thick, yang, pretty, positive, and harmonious. Green varieties are the best for gem green, glass green, gorgeous green and seedlings. 4. Water head: The water head is the transparency of jadeite. The higher the water head, the better the germ quality, and the more precious it is. When observing the emerald water head, it must be very careful, because the transparency is related to the thickness of the jadeite itself. In addition, the finished emerald products that have been carefully made, such as the middle of the finished product is hollowing out. Also pay attention to agate substitutes, because the transparency of agate is also better, so some people use agate color to imitate emerald. In Hong Kong and Taiwan, the transparency of emeralds is also divided into "Tong", "Fang", "Poly", "Ice", "Ying" and so on. Among them, "Ying" is the best product. 5. Earth: Emerald's ground must be good, whether it is emerald or green, the external texture should be delicate and uniform. Coordination and consistency, and take care of each other, thus set off the crispy richness. The emerald ground is the best for glass and egg whites. 6. Gloss: As a jewelry, jadeite also has high requirements for its gloss. It is an intuitive reflection of the quality of jadeite quality. It must have a strong glass gloss or pearl luster with oil. 7. feel: due to the high hardness of the jadeite, the structure is dense and delicate, the polishing is good, and the smoothness is good. In addition, sticking emeralds on the face or on the back of the hand has a cold feeling. 8. Perfect: Most refers to the perfectness of the jadeite, including no defects in the emerald, the body is perfect and non -damaged and the block is large. Regarding the internal defects, it should be dialectically treated. Generally speaking, it is better to contain black spots, stone flowers and cracks than those containing these defects, but sometimes weak defects. Instead, it is confirmed that it is the basis for the genuine goods, especially when the market is full of fake goods everywhere in today's market. In the international jewelery market, it is usually divided into three categories according to the color, transparency and structural texture of jadeite, and each major class is divided into four grades of A, B, C, and D. Category and grade emeralds are very different. The first category is Emperor Yu. It is the top product of emerald. The color is green and pure, strong, uniform, high, high, water head and foot, and its texture structure is all authentic old species. The output accounts for only five percent of the world's total output. The price of this kind of emerald is very expensive. The measurement unit is calculated in carats and ranked among high -end gems such as diamonds, Gangyu, emerald, and cat's eyes. At the 28th Yangon Gem Exhibition, the emperor jade A -class A -class $ 2,000 per carat; the B -level $ 500 one carat; the C -Class $ 200 one carat; the D -level $ 100 per carat. The second category, called commercial jade. The grade is not as good as the first type of emperor jade, the colors are relatively complicated, and the jadeite of various colors is available, and the color is different, uniform, and different transparency. Its pits are also complicated, including old, new, new and old species. The quality of this type of jadeite is uneven, and its high -quality people are second only to the concentration and uniformity of the color of the emperor jade. This category is a large category of jadeite. It is mainly used to make jewelry. It is the main emerald product in jewelry shops around the world. At the 28th Yangon Gem Exhibition, commercial jade A class is $ 1,000 per kilogram; B -level 200 One kilogram of dollars; C -level $ 50 per kilogram; D -level 30 US dollars per kilogram. The third category is called ordinary jade. This is the latest category of jadeite. It includes colorless emeralds. Its structure is basically the same as commercial jade. It is mainly used to make some lower -grade jade carving ornaments. At the 28th Yangon Gem Exhibition, ordinary jade A -level A -class was $ 30 per kilogram; B -level $ 15 per kilogram; C -Class $ 10 per kilogram; D -Class 5 per kilogram.
