divided by three types of occurrence:
(1) Tsai Yu: fish out of jade from the rivers, it is through the erosion of native stone, washed in water transport to the large pebbles, this jade many small, few large, good texture, full head, clean color, which often appear Aberdeen suet jade.
(2) mountain Liu Shui Jade: The removal of ice and floods, nephrite, which is characterized by blocks of large, smooth surface
(3) Shan Liu Yu: refers to the jade mines from mined in native jade.
a kind of colorless:
a kind of colorless, color is color less pale or colorless, transparent or translucent, delicate texture and jade. The naked eye can see only the individual fibrous mineral jadeite, no internal impurities, cotton lock, stone flower less, hit the crisp sound like metal. Polarizing microscope for the crystal structure of fibrous changes.
material if large enough, then, are generally used to make bracelets, bracelets showed clear, clear water good, large sparse block, a high-grade, finished product prices generally 50,000 to 15 million yuan.
Hibiscus species:
Hibiscus species like hibiscus flowers, fragrance and distant light, usually light green hibiscus colors, the naked eye The color is not pure evil, with no yellow color. Translucent or slightly transparent, more delicate jade, feeling under the magnifying glass in the 10X particles, but can not find the line, this is because in the latter part of the formation being the result of recrystallization can be said that an egg white, the kind, though not very transparent, but not dry; color, although not strong, but light, similar to the Chinese uranium Yu. Lotus seed production
larger, easier to see, much loved in southern China, the price is expensive in the north in the south, is a high-end, price is not very high in general. If the Hibiscus species appear on the deep emerald green veins, known as the
dry green types:
divided into two categories: one is pure sodium chromium pyroxene, and the other in addition to sodium chromium pyroxene, the also contains jadeite, made amphibole, etc., the proportion of 3.3 soil, such strong and pure emerald green color, transparency is poor, background, in the sun, the light does not go through with a torch light condenser, can only enter through a 1mm light. This jade, jade coarse mineral particles were short columnar shape under the microscope for the whole knot at the end of granular crystalline semi-circular white as snow, engaging and bright green, green is generally irregular, there was patchy or mass. Observed under a 10X magnifying glass in its delicate texture, often showed a fibrous structure, the most opaque.
species of green white green, white and clear, generally more white background, bright green, although the head is not good, but there are many young women to buy. White, blue species is generally only suitable for bracelets, carvings, listing. Small pendant or bracelet prices generally between 1 1000-10000 yuan. Price depends on the kind of quality and range of size and green color.
cyanine species:
Myanmar jade in a wider distribution, is based on the distribution of color patterns to division. Cyanine species distribution was green veins, or more sparse distribution of more intensive, deep colors can also be shallow. Background for the light green or colorless, texture can be coarse to fine. Can be further subdivided according to texture, such as: Douhua anthocyanin,paul smith sale shop, coarse grains, beans, said the end of the irregular color distribution of anthocyanin. There are also horse teeth cyanine, cyanine and other oil base. In terms of color-shaped distribution, but also point-like anthocyanin, commonly known as Cyanine species depends on the kind of good or bad value, and color range and color. Easier to see the market, used for a small pendant, is a middle and low price in the tens of dollars to several hundred yuan.
oil green types:
naked eye: dark green, the color impurities, doping gray or blue tones, giving a very depressing feeling. Green oil is better kind of transparency, Yu Zhi Xini,paul smith wallet, shiny glass,paul smith belt, but the surface gloss like with oil. Microscopically, the fibrous crystal structure change. Color can be shallow to deep, if the color depth, known as the Green species in the oil market more easily see, is a middle and low. More popular in the north,cheap paul smith, the south is not so popular in the north due to the impact of human preferences, the price is slightly more expensive in the South. Cabochon price usually in the tens to hundreds of yuan.
horse tooth types:
textured, white granular mineral jade, transparency is poor, saying: Like the naked eye looks a bit like porcelain. Observed under the 10X magnifying glass, can clearly see the green in a very small trace of white bars, although the green than the green, but not uniform, and the irregular distribution. Species are rarely used in horse teeth do the ring face, more listed, rings, etc., kind of horse teeth easier to see in the market, is the low end, price is not high, a few dozen to several hundred dollars.
and Tian
jade, its texture and delicate, exquisitely carved, loved by people since ancient times.
Fei:
can be divided into red and yellow Fei Fei two cases. Fei red color is the formation of a secondary color, or distributed under the weathered surface cracks along the distribution of jade stones for the formation of iron minerals disseminated color, produced in Myanmar, the old field area and large Macan field area. Hong Fei can be divided into three types:
① bright red: also known as the Red: is often oxidized to Fe3 + Fe2 + caused more close to the edge of the original stone distribution;
③ Maroons: produced in the original stone edge, due to weathering and leaching caused by iron staining, with very large brown impurities , red Fei's beneath contempt.
bright red red Fei rare, scarce, prices high. The brown and dark red red red Fei, yield, because of color, rather than human love, the price is very low, a few dollars to several hundred dollars can buy.
Huang Fei is also formed as secondary color, usually located under the weathered surface, and in the red layer, which is due to Brown dip due to iron ore. Yellow impure, often with brown, yield, not well loved, the price is very low, a few dollars to tens of dollars you can buy.
Spring:
purple jade,paul smith knitwear, purple, commonly known as the Spring, usually a light purple, purple hue under different light purple can be divided into , eggplant purple, blue-violet.
① purple: purple with a slightly pink, delicate texture, translucent, internal speech more cotton, was used as a background, called
② eggplant purple: purple eggplant in like bees with red, rough texture, the mineral particles visible, poor transparency, a large number of cotton within the lock.
③ violet: purple with a blue, textured, visible mineral grains, almost opaque, percussion sound muddy, very low grade.
light for spring, so do rare face ring, used for large and small pieces of carved pendant. If deep purple, texture thin, transparent is very rare, are offers for higher quality products worth thousands, to one hundred and fifty thousand yuan a can, by European and American people like. Jade Spring in the choice of when to avoid yellow, purple for yellow will deepen.
blue flowers:
color green in the blue, greenish blue, is of tremolite, actinolite petrochemical appearance performance. Naked eye: the evil is not correct color, transparency is poor, the general texture, a large number of dirty black house, belonging to low-grade jade material, a few dollars to several hundred dollars can buy.
dirty:
is the emerald of the inferior varieties, including taro, dog feces, the ash to other, visual observation: opaque, texture Rough, large mineral grains can be seen; 10X observed under a magnifying glass: the meat department of impurities, with stone flowers, stone brain, color very straight, mixed with yellow, brown, gray and other colors in the common market, is low grade, a few dollars to tens of dollars you can buy.
Lantian
color complex and diverse, the distribution of performance on the jade two: First, dip each colored staggered, disorganized, and the other showed roughly parallel to the ribbon Fair City, and there is hue, the concentration gradient on the performance of the relationship was. Its texture is similar to nephrite and jadeite, with a tough dense and delicate nature. Its transparency from translucent, slightly transparent to opaque can be seen.

Jade
common emerald color white, gray, pink, light brown, green, green, yellow, purple, etc., most opaque, individual translucent, shiny glass. Divided by color and texture, there are gems green, brilliant green, yellow and green sun, sun smart green, glass green, parrot green, spinach green, and shallow green, light green, sun, frog green, green melons, plum green, blue and green , gray-green, glossy dark green, and violet and lotus root to other 20 varieties.
many factors affecting the quality of jade, including color, texture (structure), transparency (head), cracks, impurities, etc., affect the finished product of factors, including jade processing. In the emerald-commerce, texture and transparency will be referred to as Transparency (head) is the level of transparency. Color is the color of strong, positive, positive, and level.
jade with addition to heat, soft tendon strong bone, Ann soul, Lee blood, clear eyes and ears and long efficacy. Yu can support people who can support Yu.
jade identification standards generally were the following:
First, look at the proportion of jade. Greater proportion of the more precious jade.
two is to look at the hardness of jade. Yu Dan Yuejia hardness more powerful.
Third, look at the color of jade. Red for the kingfisher, green as emerald. Cui Fei and can be called full of gems. Of course, one aspect is exquisitely carved.
Fourth, listen to the voice of jade. Brittle are better, dumb as a bad person.
Fifth, look at work. As the saying goes: Gold has a price but jade is priceless. This sentence is not science. All of the jade is on the pounds, on the cube purchase. And combine the arts, before deciding its price.
six jade is to look at the time. Jade jade and modern jade points. Jade is the artifacts. Jade is a modern work of art. An age-old Jade, the value can Citylink.

Jade major domestic species, there are 10 kinds:
(1) Xiuyan: by fiber serpentine and serpentine leaf mainly composed of dense rock block, their colors no less than ten kinds of China's Liaoning Xiuyan Jade's main producing area.
(2) Southern Jade: the Is a dark green to light green compact massive serpentinite. There are more beautiful because of its green pattern, it is suitable for large-scale jade ornaments.
(3) Jiuquan Jade: the
(4) Lu Chuan Jade: the Origin in Guangxi Luchuan.
(5) Kunlun Jade: the Foothills of the Kunlun Mountains in Xinjiang origin.
(6) Huili Jade: the Origin Huili County in Sichuan Province.
(7) Yunnan Jade: a massive green serpentine, often containing chlorite.
(8) Junan Jade: the
(9) Beijing Yellow Jade: the
(10) Dulan Jade: a bamboo pattern with massive serpentinite, it is also known as
traditional classification of emerald too small, too complex, people in theory, the concept of debating, so we practice on the basis of the factors affecting the quality of jade summarized, the Jade is divided into: the old crater species, a kind of colorless, egg white (Hibiscus), dry clean, bean seeds, gold species, white, blue, cyanine, oil green, horse teeth species, Fei, spring, blue flowers, black, etc. fourteen feature type.
crater types:
crater colors in line with strong, positive, positive, and the requirements of the color dark green, evenly distributed , nuanced, and bright. More delicate texture, transparency is good. If there is ground glass, with strong, positive, positive, and the color, texture and better enable emerald color, colorful, this species is called the old crater of glass types (Acura). Crater production of rare species of glass, glass types of wool purchased the old crater, the general need to 1OO million to 3 million yuan / public two.
Jade hardness of 7, the proportion of 3.33. Mineral refractive index: Ng = 1.667, Np = 1.654; re-discount rate of 0.012.
is the emerald of the inferior varieties, including taro, dog feces, the ash to other, visual observation: opaque, texture, roughness, showing that large mineral grains ; 10X observed under a magnifying glass: the meat department of impurities, with stone flowers, stone brain
now for our serpentine jade total process name. Broad, including Liaoning Xiuyan Jade, Guangdong Southern Jade, Jade Huili, Sichuan, Xinjiang and Beijing Kunlun Jade Yellow Jade Ming Tombs in Beijing produced and so on. Specifically refers to a narrow Jade produced by Liaoning Xiuyan Xiuyan (the Jade). Its color varied, but white, light green is common. Its hardness is 2.5 --- 4.5; the proportion of 2.5 or so; oil sheen or waxy luster; translucent to opaque, there are very few transparent, and quite similar to plexiglass.
commonly known as China's and Liaoning Xiuyan output of the
