Hometown of jade
Smooth ground
Completely transparent and glassy. The transparency of jadeite is different from that of precious stones. A good glass bracelet looks as transparent as crystal and has no impurities.
paddy field
Transparent as water, glass luster. Similar to glass mill, with a small amount of impurities.
Bingdi
Ice is second only to glass, which is as transparent as ice, that is, if there is a mist in bright light, it seems that water is frozen and stagnant.
Egg-green land
Texture like egg green, glass luster. Translucent, but relatively pure, without impurities.
Snuff land

Qingshuidi
The texture is transparent, but turquoise is a water variety with turquoise, which is not as good as water variety because of color interference.
Huishuidi
The texture is translucent, but it is light gray. Because the color is gray, the quality is worse than that of clean water.
Purple water drop
The texture is translucent, but purple. Unlike violets, they emphasize transparency and are actually translucent violets.
muddy water

Shit land
Brown, dark brown. There is a jargon called "a two-color and three-craft, the variety of bracelets and the color of pendants". It can be seen that variety, color and technology are the three most basic factors in choosing jadeite, followed by size and weight, uniformity, cleanliness, willow crack and aesthetic feeling.
1. Look at the planting water
The image of "planting a well to cover three ugliness" shows the importance of jade species.
Water head, or transparency, refers to the ability of jadeite to transmit visible light. There is a jargon: "bracelet depends on the type, pendant depends on the color." It can be seen that the head of the jade bracelet is important. A good bracelet can make a woman look younger and more energetic.
The order of species from high to low is: Laokeng glass species, water species, ice species, ice wax species, wax species and other species, and other species mainly depend on color.
judge colours
There are many colors of jadeite, but the best jadeite is mainly sunshine green. However, green has different meanings for women of different ages, figures and temperaments. When shopping, you should choose according to your own preferences. It is best for young women to choose bracelets with bright colors and good water head to look young and energetic; For elderly women, you should choose a bracelet with a darker color, which looks noble, dignified and calm.
The color grades from high to low are: green (King Green, Zhengyang Green, Apple Green), red, yellow and purple.
3. Look at the craft: There is a saying that "materials and workers share equally", which means a good work, and the value of materials and workers accounts for half; The quality of craftsmanship and symbolism have an impact on the price.
4. Others: Jade with the same size and thickness is of course thick and expensive; Uniformity, that is, water and color are uniform, and it is better without water difference and color difference; Clean means there are no flaws or other noises, and the cleaner the better; Willow leaves are cracked, that is, no cracks, which is better; Aesthetic feeling is the overall feeling of jade objects in many aspects, which also varies from person to person. The processing of jadeite products can be divided into bare products and carved products.
Bare products have high requirements for raw materials, and there can be no cracks, because cracks are easy to see. Jadeite with cracks is mostly used to make flower pieces, and cracks can be covered by carving.
Therefore, in the evaluation of nude products and flower pieces, under the same quality, nude products are more expensive than flower pieces except for particularly exquisite jade carvings. 1, transparency: translucent is the best, too transparent or opaque is not good.
2. Structure: The finer the particles, the better.
3, clear: the best without flaws.
4. Cutting: the design of "cutting the jade without cutting the abrasive", finely crafted modeling, polishing and novel styles. (1) Super grade: bright green (emerald), apple green, glass floor (translucent, fine texture), even and bright, without impurities and cracks.
Commodity grade: green, oily green land, slightly transparent, translucent grandmother green veinlets and mottled green.
③ Ordinary grade: lotus root powder mill, bean green, light green, fine white and slightly transparent. Opaque jadeite is generally only used as jade ornaments. There have been many discussions about the skills and knowledge of gambling stones. To sum up, it is nothing more than grasping the following points.
Field appraisal: Wulong River basin, a tributary of Qindun River in northern Myanmar, is a high-quality jadeite mine. There are hundreds of new and old mines (pits) within the scope. The terrain is hilly, the river valley is flat, the forest and grass are lush, the rainfall is abundant, the annual rainfall is more than 3000 mm, the quality is good, and the output is large. The new market mouth is highly valued by merchants. The stones produced in the deep are marked by red wax, black wax and white yellow wax shells. It should be pointed out that there are many jade yards, and each yard may be produced.
In addition, there are crack types such as size, opening and closing, which have great influence on evaluation, processing and utilization, and are a major defect of jadeite. Insiders said that they are not afraid of big cracks or small cracks, and would rather gamble than gamble. In gambling stone trading, we should pay attention to the outside of the big face, such as double face, big face, evil face and so on. However, the small side and the inner side are relatively weak, so we must be cautious. Experts pointed out through research that the damage degree can be judged by the color of the lock. White is a general rupture, and if it is red, yellow and black, it is a serious degree. These are the characteristics of open cracks, and those with no obvious color belong to micro-open or closed cracks. The internal cracks of finished products and Ming products (open-door jadeite) should be carefully observed, such as porcelain cracks and ponytail cracks, especially green cracks and dislocation cracks, which have a direct impact on their pricing and sales.
1. False chip opening: make a small hole on the colorless low-grade gambling stone with poor water head, and paste the high-quality chip to make it sub-optimal. When identifying, we should carefully check the adhesion marks around the opening (door), the influence of gap shape and temperature difference on it.
2. Fake leather shell: Glue inferior materials, waste stones and fakes with high-quality jade leather shells, and then bury them in the soil soaked in acid and alkali to make them look like "genuine leather" to cover up artificial traces. First, clean it with water, check every point and every surface of the shell, and don't let go of tiny holes, cracks and holes, and compare the changes of color and particle size.
3. pseudo color: Coloring and dyeing turn colorless and light-colored materials into bright turquoise, as well as waxing, painting and deep mud. During identification, the color of enamel turns red with a color filter, and the color distribution changes with a magnifying glass. The artificial coloring in the tiny cracks is heavier, and the other parts are lighter or colorless. Before observing the change, wash and heat it slightly.
4. False heart: Dig the heart to take out a part of high-grade jadeite, leave the high-grade jadeite on the skin, and then inject lead and other substances to seal the incision. If the weight is too heavy or too light, it may be fake. For the outer skin, you can use a chain and a knife to scratch whether there are uncertain soft objects and look for signs of sticking.
In the long-term practice of jade processing and production, the predecessors of China's jewelry industry have summarized a lot of experience about jade, and expressed these characteristics of jade in the form of concise aphorisms. Remembering these maxims and being able to understand and appreciate their profound connotations will benefit you for life.
