Also known as emerald jade

 Jadeite, Burma Jade, is a kind of jade, the color was emerald green (commonly known as Green) or red (termed Fei). Geological process is mainly formed by the jadeite, omphacite, and the composition of sodium chromium pyroxene jade level to polycrystalline aggregates. Also in the anime also has to

English name of the jadeite, from the Spanish abbreviation plcdode jade, which means wearing the jewel at the waist. The name emerald comes from the bird, the bird's plumage is very bright, male red feathers, the birds were Fei, female plumage and green, were Kingfisher, collectively known as jade, so the industry has for the mother Fei, Tsui for the public view. Ming Dynasty, Myanmar jade came to China to as a



pyroxene jade is a kind, monoclinic, complete cleavage. The main component is sodium silicate (NaAlSi2O6, gem minerals containing more than 50% of sodium silicate is regarded jade), produced at low temperature under high pressure metamorphic layer generated. Often associated in the blue amphibole, muscovite, lawsonite (dihydrate calcium feldspar), aragonite and quartz. Between Mohs hardness of 6.5-7, specific gravity 3.25-3.35 between the range of 900-1000 ° C between the melting point. Jade is the broad sense has commercial value, to jadeite rock gem trade names, is a gem jadeite rocks of various colors in general. The concept of a single narrow those emerald green jadeite rock gem. Geology mineral called jadeite jade is the minerals pyroxene mainly composed of fibrous aggregates, and mainly Cr (chromium) for jadeite rock coloration element. To achieve a single emerald gem from the component perspective, very close to the theoretical value of the jadeite. Is one of the most precious and most valuable jade, known as the Also because some countries and regions by the Oriental people's favorite, which is the international jewelry industry known as Jade is not rare in early, worth is not high, not paying attention to the world, Ji Xiaolan (1724--1805) in Also, I remember childhood, ginseng, coral, lapis lazuli, neither expensive price,cheap UGG boots, this is day. ...... Yunnan Jade, Yu was not to regard it, but as Wong Tin dry, strong name to Jade ears, this was curios, prices far out of true jade carry on. It can be seen, the early 18th century, the ancients do not think Jade is Jade, Jade low prices, to the 18th century, emerald is a costly curios. According to Jade stones lacking in essence, when the price is expensive, but now, one kilogram of grade seven or eight hundred thousand dollars compared to jade, simply pale into insignificance. Jade mining, transportation, processing, marketing has always been for the people of Yunnan. Rochester in Myanmar's ancient capital of Emo Luo fill a Chinese-style temple, the inscriptions engraved on the 5000 Chinese jade business name. Ming Ye Gaoguan eunuchs stationed specialized procurement Baoshan Tengchong Jewelry. Yongchang vault was to Myitkyina in Myanmar from the line already has a Tengchong Road to the most prosperous business in Myanmar has more than 20,000 horses a day when horses through them, Tengchong jewelry jade in the world trading transactions accounted for almost 9 percent. By 1950, overseas Chinese in Myanmar in Tengchong County of more than 30 million people. Even today, people in Myanmar in Yunnan jade industry tens of thousands.

(1) Chemical composition: sodium aluminum silicate - NaAI〕 〔Si2 O6, often containing Ca, Cr, Ni, Mn, Mg, Fe and other trace elements. (2) Mineral composition: The main jadeite, with minor omphacite, sodium chromium pyroxene, aegirine, amphibole, albite and so on. (3) Crystal Features: monoclinic, often has columnar, fibrous, felt-like dense aggregates, in blocks of secondary raw material for the gravel-like. (4) Hardness :6.5 - 7 .5. (5) cleavage: fine aggregates no cleavage; coarse particles can be seen in the section on the shiny (6) Light: oil sheen to the glass luster. (7) transparency: translucent to opaque. (8) relative density :3.30 - 3.36, usually 3.33. (9) index :1.65 - 1 .67, 1.66 in the Refractometer near the border of a shadow over ambiguous. Rich colors, including green for the top grade, according to the color can be divided into three types; ①, the skin color class; refers to the outermost layer of skin the color of jade, its formation and the weathering effects. These colors for a variety of different shades of red, yellow and gray, which is characterized by the skin near the part of raw materials was nearly concentric. Red is often called the Fei; ②, to sub-color: also known as color; refers to the true qualities of jade, the color characteristics of such a variety of different shades of green. Sometimes black is included in the green. Often called the emerald green. (11) luminescence: light-colored jade in the long-wave UV light in the dim white fluorescent issued, no response to short-wave UV light. Jade (Jade), also known as Myanmar customary jade, jadeite produced in Burma,Discount UGG boots, Japan, the Soviet Union, Mexico, California, also have a small output of jadeite (Jadeite), but quality and output is far less than the Union of Myanmar. Union of Myanmar, Myitkyina in northern areas, the largest jade deposits in reserves, have long emerald gem mining, the supply around the world. So people only know a long time before the Union of Myanmar jade produced, so the Myanmar jadeite jade as a synonym, the scientific name Achillea jadeite, precious stones, and jade in Myanmar is an expert in the jargon (no jade in Myanmar that it is called, jade is Chinese people give to this natural spirit of the name. It is based on a jade from a bird's name, because the most beautiful gem jadeite green and red and the color of the body such as a bird So get on the good name).

Jade is how it formed? There are many magical folk legends; geologists've been referring to it as a mystery, it has been that the emerald and diamond, are deep in the crust of thousands of high temperature and high pressure conditions, crystal formation, it is not true; many U.S. Geophysicists have done a lot of simulation experiments in the laboratory, combined with jade deposits found around the world the real situation, they believe that jade is not formed at high temperatures, but at low temperatures in the high pressure metamorphic formed. Tohoku University Professor Ichiro Sunagawa, We know from the surface to the deep Earth, The depth of the more higher the temperature, the greater the pressure. But Jade is not only under high pressure at low temperature crystallization, of course, impossible in the deep part, then the pressure really come from? This pressure is due to crustal movements caused by the formation of extrusion pressure, have now been confirmed that the distribution where there are emerald deposits in the area are more intense zone of crustal movement. There is another factor: the formation of any place that has a jade albite igneous intrusion (in the basic rocks ─). The chemical composition of albite as NaAlSi3O8, so it can be speculated that Jade is in low-temperature, high pressure conditions, sodium feldspar from the silicon to the role of the rock formation. To become a super Jadeite - Jade, must meet the following conditions must be high rock Jade low calcium magnesium iron rock. Jade output in this environment is more pure, less iron to make the base is not gray. Although there are iron low iron, but the existence of a very pure and free of impurities to Jade, must also strong reducing conditions, that is generated in the reducing environment. Because in the anoxic environment, it contains the formation of magnetite and precipitation of Fe, rather than the lattice into the jade, emerald green make corrections. Furthermore, after Jade have generated several strong geological and hydrothermal activity, the emerald green transformation was positive, the water is good, the end of the super pure emerald. Condition Jade hydrothermal process is accompanied by activities, and for many different fineness of the intensity of the process. And slow down into elements of chromium-induced color should be a long time in 150-300 ℃, the optimum temperature is about 212 ℃, the chromium ions can be uniformly continuously into the lattice, resulting in such conditions Jade Green is very uniform. Emerald Premium full generation later, still can not have a large tectonic movements, or will have different sizes and in different directions to affect the quality of the crack. It is hard to have all of these requirements, which is the reason why the super rare jade.



(1) old crater kinds of jade: the business community commonly known as emerald green uniform; old crater kinds of jadeite jade is very small grains, therefore, very difficult to see with the naked eye, Need. (2) ice types of jade: a similar kind of texture and old crater, colorless or less colored, outer layer of ice species is characterized by good surface gloss, translucent to transparent, clear Shining, giving Bingqing Yu Ying feeling. Ruo-Bing Xu species of flower-shaped jade in pulse or intermittent blue ribbon color of jade is so called Ice species used jade to make bracelet or pendant. ICY colorless emerald and the Species are on the ice in the mid-level file or jade. (3) emerald water species: the structure of its slightly rough jade glass types in the old crater, gloss, transparency is also slightly lower than the old crater of glass types and species with similar or equivalent ice. It features water transparent but glossy soft, micro its internal structure, can be seen a little of the impurities, cotton willow. Water experts say there is a species of emerald pale or colorless, slightly lower quality of the old crater kinds of jade. Emerald in the middle and upper stalls, occasionally on a variety of stalls. (4) Violet Jade: This is a color like purple violet flower jade, violet jewelry industry in turn is called With Jade is generally not on the deep purple, emerald sector according to the different shades of purple hue, purple to jade into the purple, eggplant purple and violet, purple is usually fine texture, transparency is better, followed by eggplant purple, blue Purple third. (5) Green Jade white: white youth is characterized by the end of white snow, green on white base on



looked very bright,UGG boots cheap, white and green clear. Easily identify the species of emerald: green on white background was patchy in distribution, transparency is poor, or slightly transparent to opaque; jade inlaid with fine fibers and structures, but mainly fine-grained structure; observed under the microscope ( to be 30 to 40 times magnification), common hole or uneven surface structure. This variety is mid-range emerald, a few green and white is clear, bright green color and good shape, color, end of well-coordinated, high-end products up to grade. (6) anthocyanin Jade: the color green vein distribution was very irregular; texture Rough is fine and translucent. The background is light green or other colors. Such as light gray or green beans, its structure is mainly a medium-grained and fine fiber structure. Cyanine green jade is characterized by uneven. Some are relatively dense, and some are more limited and there are shallow with deep color. There is also a structure of anthocyanin Jade only grainy, a sense of lack of water, its badly designed, so the transparency of the often poor. Anthocyanin is a mid-range or medium and low grade of jade. (7) Red Fei: red or orange color of jade, it is easy to see in the market. Red is the color of Fei



crystal growth after the formation of jadeite, the Department of disseminated hematite due. Characterized by bright red or dark red, good red color Fei Jia, a shiny glass, its transparency is translucent, red Fei products often middle and low mid-range or products, but there are high-end red Fei: color Zeming Li, delicate texture very beautiful, is loved by the people, with auspicious color of jade. (8) Wong Fei-brown: the color from yellow to brown or brown yellow jade, less transparent. This series of color of jade products in the market everywhere. Their color is generated after the formation of jadeite crystals, often distributed in the red layer on top, is caused by the disseminated limonite. In the market, the value is higher than the red Fei Huang Fei Huang Fei Fei is higher than the brown, brown and yellow, followed by the price of Fei. But there are also loved by people and to prices of jewelry unique and different from the conventional situation. (9) beans Emerald: short beans, jade family is a very common species. (10) Lotus kinds of jade: Short Hibiscus species, this is generally pale green variety of jade, free of yellow color, green, in a more clear, pure, and sometimes the base slightly pink. (11) kinds of jade horse teeth: its texture, although smaller, but opaque,UGG boots, shiny surface like porcelain. (12), lotus root starch kinds of jade: its delicate texture as lotus root starch, the color was pale purple (light spring), is a good arts and crafts materials. (13) wide film: its characteristic is obtained in natural light dark green or black, coarse texture, relatively dry head. (14) Beatrice kinds of Jade: This is a texture, color and taste of jade in the market is in the high grade jade. (15) gold species: being contained in the shallow end of the yellow, orange and yellow colors were strip-shaped, filamentous structure of parallel and directed development of clear emerald, except different color and Beatrice, the other features and Chui species of the same wire. But usually less than the price of gold kingfishers kingfishers Beatrice. (16) Oil Green Jade: Green referred to the oil or oil species, and its transparent and gloss seems to have oily feeling is everywhere in the middle and low market jade, often the production of pendants, bracelets, also made of ring plane . Oil was impure blue green species, with gray and blue components, so the more boring, not bright. (17) Bashan Jade: , is a low grade, containing amphibole, albite and other minerals of special jade. (18) dry white jade: a coarse texture, poor transparency, white jade white or light gray. Jade expert on its evaluation is: kind of rough, dry water, not run. Colorless or light color of this species, with the naked eye can see the boundaries between grains, so the rough surface structure, low use and ornamental value, is a low level of jade varieties. (19) Mexican Villa: at first glance, shiny black, very easy to make mistaken Dushan Jade in black jade, black jade or other stone, but in transmitted light observation, it is translucent, and black in through the green, especially the thin sheet of ink Tsui, in transmitted light the color is gratifying. Myanmar people, (20) Citroen Health: is a kind of bright green, but varying shades of color, transparency is poor, loose structure, columnar crystals were arranged in a certain direction of mid-range jade, can often be seen in the market. Jade

evaluation of > as a

to completely transparent glass, glass luster. The transparency of jade and precious stones are different. A good glass to look transparent as crystal bracelet, no impurities. Inferior to the glass of ice to the ice to ice the whole thing transparent, brightly lit in the case that a layer of mist, like water frozen, stagnant. Water to clear water, shiny glass. Similar to the glass to have a small amount of impurities. Texture as the egg to egg blue, shiny glass. Translucent, but more pure, no impurities. Texture as snot nose to the glass luster. Translucent, but more pure, a small amount of impurities. Geology in transparent blue water, but the Fan Qing green is green with water to species, because of color interference, as the water in varieties. Translucent gray water to the texture, but the pan-gray. Due to gray, blue water off than the quality of land and poor. Translucent purple water in texture, but the pan-purple tone. The difference is emphasized with the violet and transparent, in fact, translucent violet. Texture and translucent, like muddy water. To poor water transparency. Thin white, translucent, delicate white color. If the gloss is good, it is a good jade material. To translucent white sand, a sandy, white. White, not thin and delicate. Fui Sha to translucent, with sandy, gray. Not fine white sand to gray. To translucent green beans, green beans, to son. Translucent blue in fact varieties of beans. Purple to translucent, with uneven purple. Violet is the color uneven. Blue and white to translucent to opaque, with blue stone flower. Uneven texture, only suitable for carving. White to translucent to opaque, quality rough stones also Huaci to translucent to opaque, white.
