Perhaps it can save a 100 -eight dollar test fee. Welcome to my Baidu Space to see the relevant articles, and you can learn about the selection of jadeite appraisal evaluation. Here are some related knowledge of emerald appraisal evaluation, please refer to it.
Emerald A goods refer to the emerald raw materials except cutting, forming, polishing, and polishing. The value of emerald A goods has little to do with the value of emerald, but it is just a relatively processed B and C. rn如果说翡翠的品种呢：有A，有B，有C，也有B C，还有仿品统称D；rnA货按颜色可分：绿、白、黄、红、 Purple, black, double -colored, three -color, floating flowers, etc.;
can be divided into glass species, ice species, bean seeds, glutinous seeds, dried green, white bottom green, etc. The above types need to participate in training courses for rich specimens to grasp.

The people think that the assessment of jadeite is very esoteric and can't touch the mind. In fact, the good or bad of the jadeite is the assessment of jadeite. From the four aspects of color, species, size, and craftsmanship, This is consistent with the diamond evaluation system 4C. 4C is also color (color), clarity, carat size, and cut (cut).
color: the color of the diamond is whiter, the better, the color of the jadeite is better. The other color of pure green green, this green is too small, people call it "emperor green". The green color of the blue tone looks deep. The jadeite of this tone is often very good, and the jade feels stronger. People often say that "emerald green" jadeite is this color. The northerners' white skin, and the deep tone is closer to the character of the northerners. The yellow tone of green looks gorgeous and lively, like "poplar green", "seedlings green", and "golden silk green". Yellow -heavy emerald. Many high -end emeralds are blue or yellow in green, but if the color tone is gray, it can only be medium and low -end jadeite. The gray span is wide, from white to black. The green is white, which is "bean green"; the green is black, which is the "oil green" of the experts; there are many colors of gray in green, and many low -grade emeralds are gray.
The saturation: the higher the saturation, the stronger the green, the more precious; the low saturation, the light green, the not precious.
Inversion: In the emerald ore, green is like life, and it will never be distributed flat. It will be a line for a while, a group of green flowers, a plane for a while, and a while again. Several green spots. Even in the same material, the green is sometimes thick, sometimes light, sometimes pure and sometimes many impurities. Sometimes it is green and black, and there will be many black spots and black flowers in green. Therefore, the experts say that green has "color roots", the color comes from the root, and the color is long, which is really mysterious. It can be seen that there are very few colors in the jadeite, the better the even.
In addition to green, there are many colors such as purple, red, yellow, gray, white, brown, blue, black and so on.
The purple emerald is also called "violet", which is a very beautiful color. The purple emerald is also "thick, yang, positive, uniform", but purple is not as good as green. The price of the good Zicui is also quite high. In recent years, a pair of violet bracelets and a bunch of purple bead chains can be sold for millions at the Hong Kong auction. Just ten years ago, Zicui's price was much lower. If you invest in Zicui at that time, it must be greatly appreciated now. In fact, the amount of Zicui is much lower than the green green. Maybe the price of Zicui will exceed the green green one day. Bold ideas may also be realized, just as colorful diamonds were regarded as inferior quality products in diamonds decades ago, not enough, and now the price of top -grade color diamonds is millions of dollars. Decades ago, a collector in Europe specially went to various processing plants to collect color diamonds that were unwilling to leave at low prices of various processing plants, and today his collection has become a treasure.
The red and yellow emerald is called "emerald", and the value of jade is lower than violet. Emerald is often located in the epidermis of emeralds and is formed by oxidation. There are more emerald yields, but there are fewer kinds of centers, and red jade with uniform coloring color also has a certain value. In 2003, a string of ice -breed honey -colored necklaces also auctioned hundreds of thousands in Hong Kong. This was an absolutely unexpected price before. For a while, Luoyang paper was expensive, and Ice seed honey began to popular.
White, only ice and glass emeralds are valuable even white, because the species is so good that there is no color. The retail price of white ice and glass species can be from hundreds of yuan and thousands of yuan to tens of thousands of yuan. Because there is no color, its value is completely determined by species, size, impurities and processes.
The black emerald is also called Mo Cui. Some experts say that when you open it on the mine, you have to ask the monk to read the scriptures, so Mo Cui has a kind of evil spirit to avoid evil. It is said that the Taiwanese police love to wear Mo Cui. In addition, black is also very fashionable. There are young people who like white gold inlaid inlaid jewelry. They have the "jade" meaning of emeralds and avant -garde fashion. It is more "cool" with clothing. Mo Cui's price in recent years has also been high.
This non -green emerald prices have risen in recent years, which may also be full of resources. People unconsciously expand the jadeite collection door category, increase supply to meet the growing demand,
Cleecentness and seeds: Cleecentness: Cleecentness Refers to the degree of impurities, the less impurities, the higher the clarity. Diamonds have very high requirements for clarity, and it is best to see defects in ten times the magnifying glass. The jadeite does not have such a high requirement, because the jadeite is combined by many tiny minerals. It is inevitable to have impurities. As long as the naked eye is used, there is no particularly obvious impurities even flawless. Black flowers, white cotton, and cracking are often affected in jadeite. In the precepts, if these impurities have these impurities, the impact on value is greater; in the flower parts, these impurities have little impact on value. As the saying goes, "no flowers do not make flowers", there will be impurities in the flower parts. Crack exists.
For emerald, it is more important than the precautions, which is the degree of transparency. Emerald is composed of many tiny jadeite minerals. These small minerals are intertwined with each other, forming a felt structure. The larger the granules of mineral crystals, the more opaque emerald, the worse the seeds; the smaller the granules of the mineral crystals, the more transparent the jadeite, the better the seed.
The species is the key to watching Cui. As the saying goes, "laymen look at color, look at the species in the interior", if you can distinguish the emerald species, you can see that Cui has been introduced. rn对于外行来说，比较困难的是翡翠的种份没有一个系统的体系，行家也多是用一些形象词语比喻，像玻璃种、冰种、金丝种、油种、豆种、 Porcelain land, dry white land, pouring ground, snoting, etc., are species, and the ground, the difference can only be intention and appreciation. In fact, there is no mysterious, because there are many culture of the old experts, but just by faith in the model metaphor of life, as long as you look at it, it is no problem. However, for buyers, this division is unnecessary and unscientific. I advocate that according to the crystalline particles from thin to thick, I simply divide the jadeite into glass, ice species, oil, beans, and dry white species. Level 5, other common hibiscus species and glutinous species can be included in bean species, golden silk can be included in ice seeds, green and white -bottomed green can be included in the bean species, and the porcelain bottom can be attributed to dry white species
The ice species jade dragon Pei
is also called "water", the so -called "planting water" also. Species are described, and water is a magnitude of magnitude. Old experts often take water three levels, so -called one to three points of water, but often some emeralds only have half water, which is not simple to use. For buyers who buy emerald at the auction company, I help them divide the emerald's water to the tenth level: the glass species is 9 to 10 water, the ice species is 7 to 8 minutes, the oil species is 6 to 7 divisions, the finer is thin, thinning Beans are 5 to 6 minutes, rigid beans are 3 to 4 minutes, and dry white species are 1 to 2 parts of water.
The "Iron Dragon Sheng" (also known as "Tianlong Sheng") on the market is only 1-2 parts of water. Its color is very good, that is, the water head is too poor, and the thickness is generally processed to less than 1 mm. Some are even as thin as paper. This emerald looks very beautiful, but it is very easy to break.
: The same color and species of jadeite, of course, the larger the more precious. The same material is made into small flowers. It may be low -end goods, and the entire piece of large ornaments may become high -end products.
cooperating with size, the impact of the category of emeralds on value is also very large. If the same size and flowers of the same size are the same color and species, the price of the noodles is much higher than the flower parts, because the requirements of the precepts are high, there must be impurities, cracking, and uniform colors, and the flower parts should be uniform, and the flowers must Most of them are made of materials that are not enough. There are also people strange: Why are the price of some beans higher than the glass? This situation is very common, because the bean species may be better in color, and the color value of the glass species is lower; in addition, the category is different. Generally, it sells only a few thousand dollars with colorless small flowers.
The process: process can be divided into unqualified, qualified, wonderful levels.
The traditional jade processing method has been used for thousands of years. Although the process value is not as heavy as the jade finished product, it will still affect the value of emerald. The unqualified processing lines are rough and the connection is not smooth, which will greatly degrade the value of emerald. Fortunately, the emeralds of this inferior process are becoming more and more marketable. I remember a few years ago, a rough Guanyin ornament was sold somewhere in Beijing, and the price was not low. If you want to come, this situation will not happen now.
In contrast, wonderful processing can increase the value of emerald. "Qiao Zuo" means that the different colors of natural jadeite are cleverly used. Good processing can greatly increase the value of emerald.
For emerald consumers, consumer jade jewelry is not where to buy, nor is the price high, the key is that you like it, and the cost -effective is high. Seeing the certificate, first search the "institution name suspected illegal" to see if there are negative news, and some are required to issue another certificate, because such negative news may cause distrust of the quality and price of the product itself. You can pay attention to the following aspects of buying emerald products:
1. My personal preferences and economic tolerance, and choose to buy your own baby at the same price.
2, the size and style should be suitable for you.
3, the general emerald evaluation should be considered: the more positive the color, the better (such as green is the right green, the gray is gray), the better the more transparent, the more delicate the structure, the better, the carving is delicate and split.
4, cargo than three
5, the authority of the inspection certificate (CAL, CMA, CNAS is indispensable)
6, the content of the testing institution has been updated quickly, and the content is rich, not just to check the certificate, just exist to exist It can reflect its investment and authority.
7, choose a good baby, do not rush to buy, send it to the netizen to help you with your staff.
If jade A, B, C goods themselves to identify tips:
1. Observation of light, whether there is a faint yellow tone out, and if there is It can be determined that B or B C (exception: except for the white -bottomed green species, the long time of B goods will turn yellow). 2. For crackless bracelets, use other non -bracelet jade to knock on, and it will make a crisp sound of Ding Ding, and the sound of goods B is not so crispy. It can be compared with the OK A carrier bracelet.
b The principle of paleness of the goods: B is a natural species -like emerald raw material. After being soaked in strong acid and strong alkali for a few months, it is made of vacuum injection. This process reflects the natural emerald granules. Therefore, the B goods will show unnatural pale body color on the finished product. 3. Careful observation of C goods can be seen in spider web -like distribution.
