Jade and false identification _ venture

Jade and false identification ① view gloss: true jade whether translucent or opaque, soft sheen, internal clips have a small amount of impurities or solid batting-like patterns are normal; false jade colour dry, dull dull without aura, there are bubbles. ② the hardness measurement: engraving, scraping with a knife, true jade without leaving any traces. True specific gravity: ③ twist jade feel heavy, leave the freshness. ④ hear sounds: the Jade wire suspended pending, with a hard object percussion, melodic sound of authenticity, and graceful melodious; false is relatively dry and boring. ⑤ see fracture: 10 x magnifying glass observation of fracture surface of the true jade is mixed, comparison and dense structure is visible; false Jade of fracture surface neat shiny, often for glass fracture surface structure class imitation, rough, no waxy luster is stone imitations. How to identify genuine and fake of the Jade (ZT) jade is a kind of esoteric special culture, it is overflowing with the various historical periods. From "Jade" words of Chinese characters have about 500 people a description of the good things, many have added a "Jade" things, such as foot and hand, yurong, Yuh, jade body ... Even sacrificed for Justice, but also to "jade pieces" to describe. Jade wide meaning, in General, natural generated, after processing into delicate even damp, colorful, texture tough, stable chemical property of beauty stone, can be subsumed under the Jade class. People usually say that jade is in fact a soft Jadeite jade and. Nephrite refers to tremolite-actinolite mineral composition of jade, that is, white jade, jade, jade Qing, Topaz, etc.; jade refers and nephrite jade character nearest from Burma jade. But the diamond, Sapphire, agate, coral, such as coal and Crystal, tortoise shell, is the "jewel" of organic matter. There is a comparison of hardware and software requirements of jade, is denser texture, color and luster is crystal clear and beautiful. Chinese jades of Neolithic age, the oldest data found in the years from 1.2 haicheng, Liaoning, it ruins the fairy hole is a stone of serpentine stone. Later, as the milling technique invents, people finally regularity to see there are a number of stone by grinding system showed an especially fine Kit, the beauty of the material. Although it is unknown as jade, but intends to elect for the decoration of the body. The people at the beginning of the play-due to a lack of understanding, the fear of experiencing a fake. Currently on the market of glass always products, I'm afraid is a fake identification in the most general, most simple one. Commonly referred to as the "Emerald" naked round ring, small dog, jade plates etc. This kind of glass products because it is poured into a mould, a high temperature of glass when van solution in how many pieces of edge will overflow, cooling after becoming dull raised van line. Fingered, seeing will be found. If you get a magnifying glass reflects light observation, of which a large bubble. If you do not ask the expert, who want to own jade identification of genuine and fake, jade from three angles: first, because the glass is very crisp hard texture, structure and arrangement of dredging, the lack of robustness of dense and jade, could not afford to high-speed rotary engraving of strong, so the glass General processing out high-relief and round sculpture. 2. use the magnifying glass to find bubble, even if you can only see one can confirm is jade. 3. glass joined chromium oxide, color near the Ruby; join the cobalt oxide, color near the Sapphire; join the chrome and copper oxide, color near Emerald ... So on, there is a good variety of fake jade. But their tone was always thin, lack of natural jade color of oil, a rich feeling. New jade and identification of jade. New jade and false identification focus on variety, texture or bad and decor of roughage. While Jade's identification of relatively complex, in addition to the new jade a few basic requirements, but also recognition of the jades and its historical value. The historical value of jade, is to explicitly age-based. To be familiar with all of the common era of the jades shape, distinctive technology, color quality, you can often see books about jade and information, in depicting the jade dating a rational levels. And the physical contact as much as possible, you can correct the book picture with real disparity between. How to identify genuine and fake jade at present, some sold on the market stalls, often of jade and mixed in some processing superb artificial jade. Reliable identification method is: see, hear, and testing. See, the main watch crystal transparency, jade transparency, oil sheen; listen to sound crisp, true jade, whereas sound dull dumb; testing, jade crossed from glass, glass left scratching, and jade itself the whole. Common false jade have plastic, tinted glass, stone (marble), electric color ·true jade crystal powder and added salt are made of synthetic imitation by Glauber child class jade and other different do leave the differential method, which means also varies. Plastic light texture than jade, hardness, and generally also easily. Coloring is also easy to distinguish from work. As long as the light or sunlight check, you will see many bubbles inside the glass. Comparison of difficile is denshoku ·true, this decree after plating, to poor quality jade plating a beautiful emerald green appearance, is easy to mistake is jade. At this point would require careful observation, if there are some green with blue small cracks, is false. Because when you leave a crack, plating experts called "spider-claw". Some people say that the electric colors leave jade placed hot oil, plating color will fade, but its true. Jade crystal powder, and salt water synthesis made of jade to imitated dark old pits jade. Identification method is very simple, that is, their proportion is different. The proportion of natural jade, 3.3-3.4 synthetic jade proportion only 2.8. OK OK severity by hand, or balance weighing to tell. Child with NOx, imitation jade look than jade also white moistening. The ancients said: "Jade game NOx, will be high. "That is, white jade to oscillator as NOx, is advanced. Visible, NOx and jade difficult to distinguish. But the truth is different. The colors, white, white, often pan-green-white, rare, and sodium child is uniform net pure white. The Jade of soft and delicate, jade, such as lipids such as plaster, although soft NOx child, moistening they will inevitably be a thief. White jade is a natural product, the Constitution is very difficult to completely uniform, in jade, jade flower, etc. NOx child made for artificial, then no such image. White jade quality solid, no bubble. NOx child process, often have a bubble, gas eye exposure. Find out which is not the son of nitrate products as jade. (A) and nephrite jade distinction we oftenHeard phrases such as "nephrite, Taiwan jade", "Canada jade"; and "óñ, jade, jade, jade", etc, it belongs to the Mineralogical called "soft jade". "Soft jade" in our ancient scriptures and has not been seen in, is derived from mineralogical in modern times. Nephrite was amphiboles group minerals consisting of special aggregates. According to its colors, soft jade can be divided into: white jade, jade, jade, jade, Topaz, candy jade several important varieties. Nephrite Jade's different distinctions and at are: 1. Soft jade color uniform, white, dark green, dark green, no fresh green. 2. soft jade solid oil sheen, no green. 3. the proportion of nephrite (3.00) is slightly higher than the proportion of Emerald. 4. index of refraction of nephrite (1.62) is slightly better than Jade's refractive index. (Ii) "Malay jade" and Fei distinction, in the 80 's jade market a green bright and uniform made of jade, or beaded ring face, once fooled many people think that it is "a rare luxury Emerald". The Jade lie? this jade called Malaysia Jade (MA, also known as ' maleated Chui "), this is just a name. Malaysia jade is not produced in Malaysia. It is the number of India and Pakistan businessmen in mainland China opening up large amounts into Yunnan borders in the early days of selling a false name of Emerald. Malay jade is in fact an dyed Green very fine-grained quartz rock, but compared with Emerald significant differences : 1. Visual inspection, Malaysia jade color too bright and very unnatural. 2. Malaysia jade 2.65, far less than the proportion of Jadeite 3.24 ~ 3.43. 3. the average index of Malaysia jade 1.55, Jade's refractive index. 4. Charles filter under the red color will not change, but at ten times the microscopically observed there, that is the color of the dye to a float is dyed. (Iii) Australia Jade (green chalcedony) and Emerald of difference, also known as the Australia jade, who is rich in Southeast Asia to Australia. Because of the color green, quite popular. It is produced, particles, lower prices, have confused some people. In fact, it is a kind of SiO2 aphanitic's stated in mineralogical chalcedony or stone cord. Australia jade strictly speaking not jade, green of chalcedony, it looks quite like Emerald, but unlike with Emerald: 1. Australia jade color too uniform, amyloid has health, few deep green, much like plastic. 2. by virtue of magnifying, Australia jade definitely don't see green. 3.2.60 Australian jade proportion than Jade (3.24 ~ 3.43) light. 4. Australia jade refractive index 1.55, Jade's refractive index. (Iv) dongling jade and Fei jewellery of the difference between the market common a medium green (the shades vary), assumes the Semitransparent beaded (also sometimes carved into ornaments), because there are green, the price is not high, quite a lot of ladies of all ages. This type of wire lie? ask the seller, he replied: "this is the India of curios, jade". Dongling jade, also known as the most dongling stone, preterm delivery in India, also known as "India-Yu". China Henan also outputs, it was called "the secret jade", however the correct name should be a Yiu Quartz. Dongling jade and Fei differences are: 1. visible light with perspective, there is a parallel within dongling jade green chrome MICA arranged. Side viewing of, often forming a "green line". Observation at Charles Lapis, green chrome mica is red. 2. dongling 2.65 jade, Jade's much smaller proportion. Free hand to weigh out. 3. the average dongling jade 1.55, refractive index than the refractive index of Emerald. (V) water (sodium feldspar Jade) and Emerald distinction, in recent years, Ruili, Yunnan Kunming in tengchong, etc. and the Mainland's major cities of jewelry on the market, and a head very well, is transparent or translucent "ice" Jade, overall color to white or grey, with fewer white and ribbons, uneven distribution, this jade in local water called "whole child", with a tint of the color to blue side is called a "floating", with blue water has often been processed into bracelets, pendants and sculpture ware in the Taiwan market. In fact, "levigation child" of the main mineral composition is albite, secondly there is a small amount of pyroxene minerals and amphiboles minerals. Simple identification may take several method: 1. Zoom observation: levigation child composed mainly by sodium feldspar, not dimmed Chui, and have more white stone brain or sponge. 2. hands OK method: levigation child specific gravity (2.57 ~ 2.64) than the proportion of Emerald much hands OK ratio Emerald apparent sense of freshness. 3. determination of the refraction index method: levigation child of refractive index (1.52 ~ 1.54) than Jade's refractive index. All in all, understanding the characteristics of the Emerald, will gain control of Emerald and the distinction is similar to stone.
