Long-term

 Young jade jewelry, more and more glistening green color is also emitted in the early summer air. However, choose your favorite style is not difficult to avoid when buying jade is taken in the first event. Therefore, to understand the classification and identification methods Emerald order to have a favorite magic items.

understand the Jade family

view of the market there are many jade jewelry counterfeit goods, so the styles of the time of purchase in addition to considering the use of some of the knowledge we have to be taken to reduce the chance. Magazine interview with GIA certificate holders (Royal Society certification jewelry jewelry appraisal qualification), practitioners in the jade industry for nearly 10 years of Miss Xiong Yin, she summed up the family to explain a number of jade in the classification and identification methods.

business classification

jade jewelry on sale, some natural jade, some are optimized processing of jade. Business based on these differences will be divided into jewelry Jade A Jade Cargo, Jade Cargo and Jade B C goods.

Jade A cargo refers to natural production, without the artificial use of physical or chemical destruction of their internal structure or material into or out of jade.

Jade Cargo B is the original species of water, poor color of jade through strong acid, alkali soaking, it kind of water, the color can be improved, at the same time, the original rock structure of jade were destroyed, accompanied by material into or out of, so called Jade B Jade Cargo. To cover up the damaged structure, increases the strength of jade, jade B goods often use organic or inorganic adhesive glue for filling treatment, but treatment is not fully plastic goods Jade B logical step, does not affect the definition of Jade B goods.

Jade C refers to colorless or light goods artificially dyed jade jewelry. There are several staining methods, both the structure of chromatin damage, there does not destroy the structure of chromatin, but the pigments exist only between emerald or intergranular fracture. Often dyed emerald green, red, yellow or purple.

expert classification

must first figure out comprehensive evaluation and title. This is a popular saying in the South, to the southern area, experts are using Green species), the meaning of species becomes different. Here are some common jade in the market variety

to divide the structure and texture. (Identification: Under a microscope, you can see it there was microscopic crystalline granular,cheap UGG boots, uniform grain size, grain invisible, pure unadulterated quality jadeite, texture is fine, no crack lock of cotton, grain, percussion sound was Yu-yi Metal crisp sound, transparent, glass, gloss, Yu-yi, like glass shape perception.)

the same. However, many black heart on the market today say what the boss at every turn, Common market, the Flowers (Identification: jadeite was fine granular crystals, uniform grain size, grain naked eye can be argued, pure unadulterated quality jadeite, texture Xirun, no crack lock of cotton, grain, or rare, hit Yu-yi, crisp sound of metal sound, transparent, glass gloss, Yu-yi shape perception like ice crystals.)

Mainly in terms of color, texture not ask for much. Plus with a gray color is mainly blue, or green with a yellow color, more light blue and dark blue of the points, there is oil in the common blue, egg blue, blue, green, etc., dull colors are not bright, but the transparency is good. Jade Cargo B looks like a lot of oil blue species, many novice fooled, be careful it! (Identification: high transparency, fine texture,UGG boots cheap, jadeite was fine columnar crystal, fiber (variable crystal) aggregates, outline of the naked eye and some are still capable of identifying the crystal, hit Yu-yi, crisp sound of metal sound.)

White Bottom Green Jade: White bottom, but floating is brilliant green, green to green or yellow or even green Yang, its varieties of green is definitely a major highlight of this. Green is the more common white variety.

Violet Jade: Deep purple, texture, thin, transparent alexandrite is very rare.

kinds of jade gold: translucent.

beans Jade: Specifically, the bean is the grain structure, similar to bean-shaped emerald, base is very thick, the transparency of difference. A lot of this stuff on the market, the price is not too high.

species

old crater Jade

species mainly used to describe the eyes of ordinary people the color of jade, this dark green uniform, which at high concentrations and rarely Yang, general fine texture, not very transparent.

if it is transparent, adequate moisture, it will look good history of color and texture of jade, from the experts called the Ying, Yang fresh eye-catching, it is called old crater glass planted. Old crater of glass types can be said that the emerald is the most high-end call, of course, is also relatively old crater of glass types have their own quality of high and low points.

species

white white green Burma jade green species in a wider distribution, characterized by smaller texture is often fibrous structure, and background are generally more white, Of course, sometimes there are some impurities, white, green blue species is more colorful, because green and white background is more than clear from the green part of the majority of block occurred, these areas are and anthocyanin species different. Most species of white opaque green, which is less than the water experts say, they think this is a new species.

bright green color is formed of chromium. Electron microprobe analysis, because it contains high chromium white so the color of very bright blue light species.

characterized by young white background white, with bright green into porphyritic distribution.

cyanine cyanine species

distribution of species was referring to the vein of the green, an emerald and very irregular, and its background may be light green or other color, texture coarse to fine can be, for example, cyanine beans at the end, its coarse grain structure, known as the beans at the end, it is irregular color, sometimes more densely distributed, it may be more limited and can also be shallow depth, so this type of jade be called anthocyanin species.

most emerald color distribution is irregular, so the more anthocyanin species is not surprising, in fact, some fine points, anthocyanin species can be further divided; bean base cyanine, MA Flowers Green, oil base cyanine ... .... Cyanine species of jade, is characterized by irregular distribution of green.

oil green oil breeding species

Jade is a dark emerald green color is not pure green, gray or mixed with some blue, so not bright, but also stresses color is very dull, and its deep color can be light, transparency is better, crystal structure, is often fibrous, to relatively small, due to its glossy surface sheen like oil, so called oil green species, if it's darker , Green oil expert also known as melons.

beans

If you walk to the Jade Market, when you see that Jade is not very transparent, the color in general, the concentration is not high,UGG boots clearanc, that is, color is not deep, if you Q. What kind of this jade? You will hear the answer to this is the beans, you will also find many kinds of jade beans are called, line the words bean

What is it? Beans is a very image of the call, we know that Jade is a polycrystalline,UGGs, coarse if the composition of emerald crystals, such as a millimeter larger than the naked eye can easily be seen, the majority of rough emerald crystals are short prismatic When these short prismatic crystals when the boundary is clear, looks like a grain of mung bean, so called beans, due to coarse particles, transparency is often poor. Experts as it is dry, is very common bean variety, poor quality, the price of natural cheap, bean seeds can be further divided into: jelly beans, ice, beans and so on. If the particle is very thick, can be rough to 3? Mm, that is, a rough co-beans.

Hibiscus Hibiscus species

the so-called species, its color is usually light green, but not with yellow, green was more pure, it was relatively clear, its fine texture than beans, structure granular will make people feel, but do not see the grain boundaries, because the later was the result of recrystallization, the general transparency can, though not of glass types can be said that the ice species, colors, although not strong enough, but clear, although not very transparent species, but not dry, the price is not high, it is easier to be generally accepted. Will be dark for the more expensive, some of the light will be cheaper, if the pulse which is called the dark green from the blue lotus root, addition of which have irregular distribution of dark green Shiyou called anthocyanin Hibiscus species.

types of gold species

gold refers to the color of jade into the trace of filamentous distribution, arranged parallel to each other, we can clearly see the green intermittently along a certain direction, and Of course, the green band can be coarse to fine.

gold species depends on the quality of its emerald green color and green stripe with a percentage of the number and thickness of the case may be, texture, color, thick bands, representing a large area ratio, color and relatively bright, high-value, of course, the opposite color with a sparse, but also a light on the more expensive.

species of horse teeth

name implies; horse's teeth is enamel, that is, horse teeth, although smaller species of jade texture, but opaque, like porcelain, like, kind of horse teeth Most of the green, rough looks good, but no species of colored, carefully watching to see the green of which a very small trace of white bars.

although certain kinds of horses the color of teeth, but not transparent, jargon, or head, said not enough water is short, so the value is not high.



This is a violet purple jade, purple jade that are generally lighter, as if Violet purple flowers, hence the name.

A careful observation of purple jade, the color is slightly different, generally speaking can be divided into purple, eggplant purple, violet. Purple relatively thin texture, transparency, some of the relatively rare, more times eggplant purple, violet generally coarse texture, but also further referred to as purple beans.

purple jade, yellow below the general view, will appear darker purple, be careful when purchasing this point. Deep purple, texture, thin, transparent emerald is hard to find, are particularly favored by European and American people.

dry green species

sodium chromium pyroxene (also known as chromium pyroxene meteorite) is not formed on Earth, only discovered in meteorites.

sodium chromium pyroxene is the original Hong Kong expert called dry green kingfishers, it generally emerald different chemical composition NaCrSi2O6, hardness 5, specific gravity 3.5, refractive index of 1.75, compared with chromium high so bright in color, but its poor transparency, coarse particles, so the experts called dry green species.

what Jade's On call are not the same emerald, emerald jade production in Myanmar this, some merchants for a nominal Myanmar jade, and our tradition called Jade, gem in the name of national norms also determine the correct call, said Jade . Natural jade in the commodity sign marked only the emerald, together with the natural rather than word processing in order to distinguish natural and man-made of jade, also known as the A goods from natural jade, the call will be processed goods B, C cargo or B + C goods. China's vast territory, the South, the North made different customs and different aspects of jade call are different, but Jade's How to identify To put forward my own understanding and awareness and enthusiasts to explore.

in the narrative Jade is a sodium aluminum silicate and jade, it is not a single crystal class (such as diamonds, emeralds, ruby, sapphire and other precious stones), but rather a collection of polycrystalline jade. Because of its Mohs hardness is 7 degrees, also known as the jadeite. Contains various oxides for the different, in which iron, chromium, nickel to show a colorful jade, the red Fei, Green Jade, Violet is everyone's favorite color, red and green like a fish in the river south of Kingfisher Therefore, this is also known as the emerald jade.

kind of jade, jade itself refers kinds of texture and transparency. Thickness composed of jade crystal, crystal density to determine the gap Jade and head their own germplasm (ie transparency), crystal fine, dense, jade will obviously Xirun, transparent, whereas thick, loose jade will become have dry, rough, opaque, fine crystal Zhixi Ni crystal gap, jade collection to the old, known as the . Jade's Shows the hardness of the jadeite, the species the older the higher the hardness, the more wear-resistant when used as something handed down for a thousand years it can damage. New species of emerald pieces of tender, the hardness decreases, do not wear, but the green will be seen within dry, there is no aura, so the saying goes, Advantages and disadvantages of species can be arranged for the glass kind, ice species, egg white species, waxy species, such as beans, fine crystal grain density to the hidden state of the glass kind, that is, the oldest species Tsui, kind of the older, transparency will the better. Coarse crystals of beans, such as peas, beans also thicker than that described it as kind of horse teeth, etc., these materials not gem jade, and no different from an ordinary stone, and now do plastic injection, goods Jade B staining crystal jewelry is the use of its large gap, by acid washing the gap after the gap in the crystal chemical injected into the gel, re-carved polished surface of the finished product will have a lot of Ma Hang, Ma, when its luster as the new wax, after using will gradually lose their light, and natural gloss surface of the glass was polished, the brighter the more you use, so do not worry about the glass on the desk will scratch it. Planted in the old colors will look beautiful psychic. Evaluation of germplasm in the emerald is the good).

The old crater jade, long story! World-renowned high-quality emerald deposit is located in northern Myanmar Wuyou River (tributary of the pro-London River) basin. From the thirteenth century (perhaps earlier) began in this area placer mining of alluvial sands and glacial until the eighteenth century only to find native emerald deposits. Native jade mining was in the Precambrian strata extending from the north east of serpentinized peridotite body. The main producers are taking degrees, Myanmar to take, take, and Nan Nai Pan risk.

by four mining vein in close proximity to each other, lenticular, composed of rock line-shaped jade ore belt in the same long, thick, nearly along the strike length of 1-2.5 km. Pulse takes the shape of ring with jade banded structure, the vein is a central part of a single mineral jadeite jade rocks, the direction of the vein wall changed to a sodium feldspar - jade rock band, rock band and alkaline albite amphibolite belt. Generally 2.5-3 m thick jade rock, mainly composed of white jadeite. The Jade is a compact (very fine to medium grain) and jadeite grain aggregates, it looks very much like white sugar-like marble (look closely intertwined with variable crystal structure of classes). In some places in the white When these mines were found, some of the veins of ore exposed in the open time is very long. As the local groundwater with acid and long-term soaking rain and erosion, the local texture of jade ore becomes more dense (because the coarse texture of the ore has been weathered pine and corrosion out) after processing showing in a very good pass through the degrees, the output of these mines were people in the emerald called the The so-called As younger, open-air development time is not enough, so most of the rough texture of pine, head missing, someone will have mountain jade ore material is also summarized in, but in fact most of the come out of his pocket! Is undoubtedly the most representative people in the known Was found to be late because of their (1983), coupled with quite a huge yield, currently used as raw materials, jade jewelry, mainly from the mining area. But the real old crater deposits in the excavation of several generations, has run out of resources.
