Emerald appraisal refers to the appraisal of emerald finished items, which can generally be divided into two aspects: instrumental testing and artificial identification. Instrument tests are usually tested by polarizers to test its structural crystals, 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 appraisal is a process of accumulation, which requires long -term practical experience to accumulate. Generally speaking, the following features need to be started: 1. Structure: The structure of the emerald is a spots crystal intertwine structure, which means that under the influence of deterioration, the small fibrous mineral crystals around the transparent granular spots are intertwined together together The structure formed. 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. Pit: The emerald pit is composed of structure and texture, and the emerald is composed of small crystals. The smaller the crystal grains, the more dense the texture is, the better the transparency, and the better the effect of the polishing. 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. Color: The color level of the color level of jadeite is reflected in great value. When identifying and evaluating emerald, it must be distinguished from its color. , Green, purple, green in monochrome emeralds, strong purple purple, and red are high -end colors in jadeite, 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 emerald. 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. Responsible, thereby setting off the richness of the emerald. The emerald ground is the best for glass and egg whites. 6. Gloss: Emerald as a jewelry, also has high requirements for its gloss. It is an intuitive reflection of the quality of jadeite. It must have a strong glass luster or pearl luster with oil. 7. Feeling: Due to the high hardness of the jadeite, the structure is dense and delicate, the polishing is good, the smoothness is good, and there is a very gentle sense of smoothness. In addition, put emerald on the face or on the back of the hand 8. Perfect: Most refers to the perfectness of the emerald, 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 jewelry market, according to the color, transparency and structural texture of jadeite, the jadeite is divided into three categories, and each major is divided into four grades of A, B, C, and D. Emerald, the price is 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 is 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 $ 30 per kilogram; B -level $ 15 per kilogram; C -Class $ 10 per kilogram; D -Class 5 per kilogram
Cargo: without any artificial chemistry. A B cargo (commonly known as high B goods): After the weak acid and weak alkali was optimized, it does not use strong acid corrosion, bleaching and glue. Therefore, the jadeite is called A B in the industry as a real to follow the real one. The B goods are differentiated to correctly reflect the value level of emerald. A B goods are still crispy and the structure is still crisp, the structure is not greatly damaged, and the market value is much higher than the B goods, second only to A goods. If it is not declared, many businesses will be sold as A goods. In addition, there is a so -called A B goods that refer to the use of the latest organic glue for irrigation. The finished products are very close to the A goods in terms of hardness, luster or sound. The difference between these two types of "A B" goods is that there are acid erodes, which depends on the distribution and cracking of the flocculent object inside the jadeite. Generally speaking Emerald, and the perfect aspect is to handle emeralds. (This is a difficult point, so say more, because many people will look here, especially if you only look at pictures or appearance, you can't distinguish it at all. Impabos such as or floc -shaped objects are the characteristics of natural emeralds.) Cargo: pickled, bleaching, gels, and the appearance of the water is very good, indicating that the gloss has a glue, the sound of the sound is stuffy, and there are obvious acid etching patterns. The price is dozens of times or more than naturally. Came C: Artificial dyeing is mostly immersed in dye for a long time, and sometimes it needs to be heated repeatedly. Note that since you want to dye, you must manually destroy the structure of the jadeite, otherwise the dyes cannot enter the interior. But this destruction may not be pickled. (Such as laser color, radiation color, etc.) But the color has no transition, no color roots. B C goods: both acid washing, bleaching, glue, and artificial dyeing. The appearance seems to be very beautiful, whether the color or the water head is very beautiful. Der goods: Physics impersonate. Regarding the appraisal of emeralds, many theoretical knowledge, scientific methods, such as what spectrometer analysis, filter observation, refractive index, proportion ... A lot of data, clearly don't understand it! However, some businesses recommend a lot of soil ways: for example, what kind of glass, burning hair, listening to sound ... Honestly, after listening to the merchant, eight Chengdu will be at the meeting: people can use a quartz rock to move the glass, burn the burn, burn it, and burn it. Keep your hair constantly, and the sound is crispy and pleasant! All appraisal certificates are particularly important at this time, and we will specifically talk about the appraisal certificate of emerald later. Traditional B and C goods are processed with low -grade emeralds. Finally, it is a serious emerald. New B and C are newly released "new pit" emeralds in recent years, which is 83 jade. It can be counted as the category of jadeite, but even more, many goods do not use emeralds to process at all, but other stones that do not match the emeralds, such as white Dongling stone from Xinjiang, etc. B, C and even A. Emerald is not like Hetian jade. Although Hetian jade high -quality jade species are relatively scarce, after all, there are relatively rich mineral support for Kunlun Mountain and Alkina, which are thousands of miles. It is not a regional concept), which is currently only output and production capacity. It seems that there are some supply in the market, and the jadeite is really dusk. There are several old pits that have less than 2 kilometers in total. Things, many emerald operators may run B, C goods, or simply change their careers, operate other jewelry or Hetian jade. As the high -quality resources of A goods emerald are increasingly exhausted, the price of B C goods in the mall has soared rapidly. The latest price of the jadeite emerald has caught up with the price of the previous A goods, and the price of A goods has soared. As for the tourist area, it is even more mixed with fish and dragons. Note: We say that "fish dragon mixed" is really polite. In fact, there are only "fish" without "dragons". Friends who know the goods and are preparing to spend money are prepared!
The emerald species are divided into glass species, ice species, oil, bean species, dried green species, etc. according to the degree of transparency. As the name suggests, the glass species is the most transparent and is the best in emerald. In the secondary plant, the oil species, the beans and the dried green species are not transparent, and the value is much lower. The degree of transparency of jadeite is actually the delicate level of the crystallization of jadeite minerals, but the crystallization of emerald rough is not uniform, and it often changes. In the past, the jadeite material was processed. It was called emerald. In recent decades, because of the production process, there are some problems except for natural jadeite, so some people think of using acid to use acid to put these black spots and dirty things in jadeite in emeralds. After melting, after melting, then pour the resin to fill this called B goods, and then in order to make this jade look better, the jadeite has no color, add color to it, fill in acid melting, resin fill, and then note the color. This is called C goods. This is called C goods. This is called C goods. Therefore, jadeite is generally divided into A, B, and C goods on the market. The "B cargo" of jadeite is bleaching glue emerald. It is mainly to remove the impurities with high impurities, dirty bottom, and lack of transparency. The impurities are soaked by strong acids and then filled by resin. Such wool will become cleaner and more transparent. Dyeing emerald, also called "C goods", is commonly used in jadeite, colorless or colorful emerald, dyed into green, purple, red and other bright colors to pretend to be high -end emerald. Emerald's B and C goods have exceeded the category of gemstones. Strictly speaking, it is equivalent to only crafts. Although they are more beautiful on the surface, its value is only one -tenth of naturally, or even one -thousandth. Because its internal structure has been destroyed, if it takes a long time, its color will change, the gloss becomes stuffy, and the color will become darker. space. Because the jadeite is mostly used in the low -grade and inferior emerald raw materials, the appearance is very beautiful after making the finished product. It is difficult for ordinary people to clearly clear the naked eye, so how to use modern technology to identify? The appraisal of jade A and B is mainly used to distinguish the instrument to distinguish the emerald containing resin fillers. The B goods are contained. One is the Raman spectrum, which belongs to the measurement of the molecular spectrum, and it belongs to non -damage. Different substances have different spectral characteristics. Using infrared spectrometers or Raman spectrometers, you can find tiny substances with a minimum diameter of one thousandth of micron particles. Therefore Essence If the composition of resin is found in its spectrum, it can be judged as B. Emerald's fake can be identified by instruments, but how can ordinary people simply identify emeralds? The easiest way is to listen to the sound. Natural A goods, the voice it knocks is very crisp and very pleasant. The emerald bracelet made of two B goods is dumb, not as crisp as A goods. This is a reference method for identifying B goods. Another method is to see that the color of the A goods is from the mineral particles. The color appears in the mineral crystal. The chromium ion enters the lattice inside the ash, so the ash particles are green. The color of C goods is very beautiful. It often looks very floating. It is one by one. It does not come from the mineral particles, but often between particles, particles in particles, and resin. Essence
The treatment of jadeite B and C can generally be simply identified: the color is too beautiful, even evil, and the water head is too transparent, but unlike the A goods, the water head of the B cargo is relatively 煳, and there are gel with gel. Feel, use a magnifying glass
