jade, its texture and delicate, exquisitely carved, loved along people since ancient times.

jade with addition to heat, soft tendon strong bone, Ann psyche, Lee blood, clear eyes and ears and long efficacy. Yu can advocate people who can patronize 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 lesson, one aspect is exquisitely carved.

Fourth,GHD Midnight Gift Set 2011, hear to the voice of jade. Brittle are better, dumb as a bad person.

six jade is to see at the time. Jade jade and modern jade points. Jade is the artifacts. Jade is a modern work of craft. An age-old Jade, the value can Citylink.




commonly known as China's and Liaoning Xiuyan output of the

and Tian
divided by three types of occurrence:

(1) Tsai Yu: fish out of jade from the rills, it is via the erosion of natural stone, cleaned in water transport to the large pebbles, this jade many small, few large, good texture, full brain, clean color, which often appear Aberdeen suet jade.

(2) mountain Liu Shui Jade: The removal of ice and torrents, nephrite, which is portrayed by blocks of large, flat surface

(3) Shan Liu Yu: refers to the jade mines from mined in native jade.



Dushan

color complex and diverse, the distribution of performance on the jade two: First, dip each colored staggered, disorganized, and the other showed roughly collateral 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 difficult dense and delicate ecology. Its transparency from translucent, slightly transparent to opaque can be seen.



Lantian
has shown signs in the appoint of Geography Since then,GHD IV Salon Straighteners, the Wife's home pass, To the Ming Dynasty, Sung in the Lam did no say jade, jade and some might even say that Lai Yu (like leaves of jade green color). In recent annuals, Shaanxi geologists discovered in Lam Tin Yu serpentinized relentless material, that it is the ancient records of Lantian (November 23, 1978 This finding not merely of raw materials reasoned by the geological community to ascertain gems care also preoccupied the interest of archaeologists. In 1982, the Department of Geology and Mineral Resources Geological Museum, exhibiting the Lantian the native stone. This serpentinized strong, the regional has convert the same with Jade jade of. Jade in arrival, with yellow, light green and so irregular intonation, and with pale white marble. This jade, though not very smart, but because Lam is situated close the ancient city of Xi'an, jade hardness to approximately 4 effortless process, so the ancients may be used as decorations. In the Han Dynasty jade, there are two like today's Lantian, a Han Wudi Mao Mausoleum in Shaanxi Province unearthed near the large jade shop door on the first embedded in the tomb; Another is the National Palace Museum of Han Dynasty jade. From these two pieces of jade and jade color point of view, many geologists deem that with today's Lantian alike. But it is really ancient Lantian, you need to be further examined.




Jade

immediately 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 restricted 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 gloss; translucent to opaque, there are very few transparent, and very similar to plexiglass.




Jade major servant species, there are 10 kinds:

(1) Xiuyan: by fiber serpentine and serpentine leaf effectively composed of dense rock block, their colors no fewer than ten kinds of China's Liaoning Xiuyan Jade's cardinal 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,GHD Rare Straighteners, it is appropriate 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 including chlorite.

(8) Junan Jade: the

(9) Beijing Yellow Jade: the

(10) Dulan Jade: a bamboo pattern with massive serpentinite, it is also known as





Jade hardness of 7, the proportion of 3.33. Mineral refractive index: Ng = 1.667, Np = 1.654; re-discount rate of 0.012.

prevalent emerald color white, gray, roseate, light brown, green, green, yellow, purple, etc., maximum vague, individual translucent, shiny glass. Divided by color and texture, there are gems green, gorgeous green,GHD IV Mini Straighteners, 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 purple and lotus basis to other 20 varieties.

many factors affecting the quality of jade, including color, texture (structure), transparency (head), cracks, impurities, etc., influence the ended product of factors, including jade processing. In the emerald-commerce, texture and transparency ambition be referred to as Transparency (head) is the class of transparency. Color is the color of strong, positive, positive, and level.




traditional assortment of emerald too small, too complex, people in theory, the notion of debating, so we train on the root of the ingredients affecting the quality of jade briefed, 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, dark, etc. fourteen function type.

crater types:
crater colors in line with mighty, affirmative, positive, and the requirements of the color dark green, evenly dispensed , nuanced, and bright. More delicate texture, transparency is good. If there is floor glass, with muscular, positive, positive, and the color, texture and better qualify emerald color, colorful, this species is cried the antique cavity of glass types (Acura). Crater product 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.



a kind of colorless:
a kind of colorless, color is color less pale or colorless, transparent or translucent, delicate texture and jade. The ########## eye can see only the individual fibrous mineral jadeite, no interior impurities, cotton lock, stone bloom less, buffet the fragile sound like metal. Polarizing microscope for the crystal structure of fibrous changes.

stuff whether large ample, then, are generally accustom to make bracelets, bracelets showed explicit, explicit water nice, large sparse block, a high-grade, finished production prices generally 50,000 to 15 million yuan.

Hibiscus species:
Hibiscus species like hibiscus flowers, perfume and distant light, usually light green hibiscus colors, the ########## eye The color is not pure malign, with not yellow color. Translucent or slightly transparent, more delicate jade, feeling under the magnifying glass in the 10X particles, but can not find the boundaries, because the formation of late been 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, many 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 adding to sodium chromium pyroxene, the also contains jadeite, made amphibole, etc., the proportion of 3.3 taint, such strong and pure emerald green color, transparency is poor, background, in the sun, the light does not bring an end to ... with a torch light condenser, can only enter through a 1mm light. This jade, jade coarse mineral particles were short columnar fashion under the microscope for the entire knot at the end of granular crystalline semi-circular white as sleet, 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 youth women to buy. White, blue species is generally only suitable for bracelets, carvings, listing. Small pendant or bracelet prices generally among 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 aboard the distribution of color patterns to division. Cyanine species distribution was green veins, alternatively more sparse distribution of more intensive, deep colors can likewise be shallow. Background as the light green or colorless, texture can be coarse to nice. Can be further subdivided according to texture, such as: Douhua anthocyanin, coarse grains, beans, said the end of the random color distribution of anthocyanin. There are too horse teeth cyanine,GHD Purple Straighteners, cyanine and additional oil pedestal. In terms of color-shaped distribution, but too point-like anthocyanin, commonly known for Cyanine category depends ashore the variety of good or bad value, and color range and color. Easier to discern the market, used because a small pendant, is a middle and low price in the tens of dollars to several hundred yuan.

oil green types:
########## eye: dark green, the color impurities, doping gray or blue tones, giving a very reducing consciousness. Green oil is better kind of transparency, Yu Zhi Xini, lustrous glass, but the surface luster 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 lightly see, is a middle and low. More popular in the north, the south is not so renowned in the north deserving to the clash of human favorites, the price is slightly more valuable in the South. Cabochon price commonly in the tens to hundreds of yuan.

horse tooth types:
textured, white granular mineral jade, transparency is poor, saying: Like the undressed eye looks a bit like porcelain. Observed under the 10X amplifying glass, can apparently see the green in a very small track of white bars, though 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.





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 according 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 rusted to Fe3 + Fe2 + caused more near to the edge of the original stone distribution;

③ Maroons: produced in the original stone edge, due to weathering and leaching caused by iron tainting, with very large brown impurities , red Fei's below contempt.

shine ruddy ruddy Fei rare, scanty, prices high. The brown and black red red red Fei, yield, because of color, prefer than person adore, the cost is quite low, a few dollars to several hundred dollars tin buy.

Huang Fei is also formed as secondary color, usually located under the weathered surface, and in the red floor, which is due to Brown submerge 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, purple, commonly known as the Spring, usually a light purple, purple hue under alter light purple can be divided into , eggplant purple, blue-violet.

① purple: purple with a slightly pink, delicate texture, translucent, internal discourse more cotton, was used as a background, called

② eggplant purple: lavender eggplant in favor bees with red, rowdy texture, the mineral particles apparent, needy transparency, a large number of cotton within the bolt.

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 an hundred and fifty thousand yuan a can, by European and American people like. Jade Spring in the alternative of while to avoid yellow, purple for yellow Huishi better.

blue flowers:
color green in the blue, greenish blue, is of tremolite, actinolite petrochemical appearance extravaganza. ########## 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 minor varieties, including taro, dog feces, the ash to other, visual observation: opaque, texture roughness , showing large mineral particles; 10X scrutinized under a magnifying glass: the pork department of impurities, with stone flowers, stone head, color very straight, mixed with yellow,GHD Red Butterfly 2011, brown, gray and other colors in the common market, is low grade, a few dollars to tens of dollars you can buy.
