Jade "kind" also called "kind of a", it refers to the crystal grain weight size, the smaller the crystal grain, the better, crystal grain is bigger, the worse kind. Coarse divided into old, new, old and new, OuYangQiuMei which is divided into: old pit kind, deep green, born TieLong, harmony sort of quyi, towel gourd green, sika deer, lotus seed, DouZhong, glass, ice, green, oil machinery, jump green, gold, green flowers, white green, "83", "82" kind of, Qatar, violet, purple jade, wuji, ruby, topaz, fu lu shou, dry green, green ink were 26 species (glass and ice kind of economical a big kinds). "Water" also called "head", refers to the jade pervious to light quality, also is the emerald transparent degree, expert will moisture for one to three points, from low to high transparency increase gradually, three baffle the most transparent, glass of which is three diversion. Another common noun called "bottom", also have an expert called "bottom water", "bottom zhang", in fact are talking emerald transparent degree, it is by the jade crystal grain size, jade felt structure the close degree decides, crystal smaller grain size, felt structure more compact, hisui transparency, the higher the water more beautiful.

A kind of learning is the concept of jade appreciation knowledge a more complex difficult to understand the concept. "One thousand kind of agate ten thousand kinds of jade", also refers to jade color, kind of a very diverse, not as simple as diamond grading. See kind of copy of the key is to see Tracy, as the saying goes "layman see color, expert see kind of", if we can distinguish emerald kind of a, then see cui has the introduction.


Emerald kind of a very much, to dilettante for, difficult is emerald kind of a not a system system, expert also is to use some image words parables, like glass, ice, gold, oil, DouZhong, porcelain, dry white, lotus root starch, nose and so on, is the kind of, it is, the difference is only sense and taste. In fact, this is not mysterious, because old expert much nothing culture, just casually use life of the template parables, but for buyers this points method real no necessary nor scientific, I compare advocate according to the crystal grain by fine to coarse, simply will jade divided into glass, ice, oil, DouZhong, flower green, green water, dry white kind etc categories.

Glass kinds: the best kind of copy, completely see crystal grain, like amorphous body of glass, completely transparent, jade internal have live light. As the saying goes "water to qing dynasty, no fish", glass kind of colorless, shallow green are rare, and have rich and gaudy green glass is little and then little, so everyone can understand a color brilliant green uniform glass types of jade ring surface, size is only 1 cm x 0.8 cm, but it can at auction sold to nearly ten million yuan, and colorless glass kind of price, with the one thousand times more than the difference.

Ice kinds: see crystal grain, translucent, no live light. Block larger, color bright full green jade flower piece of ice at auction can sell for three million to eight million, and no color ice kind of jade price difference to thousands of times.

Oil kinds: crystal grain size is very fine, like oil powder, translucent. The color of the oil slightly dark, no fresh Yang brilliant green, price and brilliant green ice kind of jade vary a lot, but northerners prefer this full-bodied tonal, sometimes even than fresh Yang color to see is still high.

DouZhong: crystal grain is bigger, the obvious, slightly transparent, color is yellow partial gray tone is green, can be divided into fine DouZhong, coarse DouZhong. DouZhong jade is the largest number of species, the so-called "ten cui nine bean". In fact good fine DouZhong jade belongs to high grade class, the price is quite expensive.

Cyanine kinds: micro transparent, crystal grain is DouZhong small, color is slightly dark green, and more green into a mass of a piece of distribution, so called cyanine. Cyanine much used for processing bracelet, flower parts, all belong to low-standard category.

Bare land green kinds: just as its name implies the jade are bare land, although crystal particles DouZhong as big, but completely opaque. Its advantages are clean uniform color, appear green is distinct. But due to the low transparency, bracelets, flower piece, prices are very low, the low class.

Dry white kinds: crystal particles, so obvious, lock of crack, completely opaque. Many processing inferior flower piece, bracelets, yield huge, also often be infected with green, used to make C cargo jade.

In addition, there is a lotus, "the gold thread kind of and so on.

If is a jade texture to the comprehensive evaluation classification of words, bottom emphasized means no color component quality of a material, expert also called "bottom zhang". Bottom is watching the raw material more use.

"Water" also known as "water". Is a description of sexual, water is the division of orders of magnitude. Old expert often will moisture level 3, the so-called one to three diversion, but often appear some jade only half water, simple classification is not enough, so in the auction company to buy jade buyers, I helped them will emerald head is divided into ten level: glass for 9 ~ 10 water, ice kind of 7 ~ 8 baffle, oil for 6 ~ 7 baffle, fine DouZhong for 5 ~ 6 diversion, coarse DouZhong for 3 ~ 4 baffle, dry white for 1 ~ 2 diversion.

Now in the market the more common "TieLong life", also called "denon life", than dry white kind of head also poor, its color is very good, is no moisture, thickness general processing into 0.1 cm below, some even as thin as paper. These jade looks very beautiful, but very easily broken.
