As early as 2,000 years ago, our people used jade for medical care. For example, "Shennong's Materia Medica", "Compendium of Materia Medica" and other ancient medical masterpieces have recorded that jade has the therapeutic effects of "removing heat from the middle, relieving anxiety, moistening the heart and lungs, helping the voice and throat, nourishing the hair, nourishing the five viscera, resting the soul and spirit, sparing the blood vessels, and brightening the ears and eyes"; 106 types of jade are used for the treatment of disease by internal service and external compresses. It is also recorded that: jade if "served for a long time to withstand cold and heat, not hungry, not old to become a god".
According to modern biological, physical and chemical analyses, many jades contain more than 10 kinds of trace elements beneficial to human body, such as gold, silver, silicon, zinc, iron, selenium, magnesium and manganese. ...... As jade is the most abundant material for storing "qi", it is therefore often used as the most important element for human health. Wearing jade can make the trace elements contained in jade inhale into the human body through the skin, thus balancing the imbalance of yin and yang, qi and blood, and enabling people to get rid of diseases, health care and longevity. For example, zinc can activate insulin, regulate energy metabolism, maintain the body's immune function, promote children's intellectual development, and has the effects of anti-cancer, anti-teratology and anti-aging. Manganese can counteract the damage caused by free radicals on the human body, participate in protein and vitamin synthesis, promote blood circulation, accelerate metabolism, anti-aging, prevent Alzheimer's disease, osteoporosis, vascular atherosclerosis and so on. Selenium is a component of glutathione peroxidase, which can catalyze the reduction of toxic peroxides to harmless hydroxyl compounds, thereby protecting the biofilm from its harmful effects, and play an anti-aging role; it can also lift the harmful heavy metals such as cadmium, lead and other toxicity of the human body, can enhance the body's immune function, improve the body's ability to fight disease, to achieve the role of cancer prevention and treatment.
The Department of Bioengineering at Southeast University has used modern technology to show that the human body itself generates a temperature field, a magnetic field, and an electric field, which constitutes a "bio-information field". This "biological information field" will produce a corresponding wave spectrum, known as "biological wave". "Bio-waves" can generate bioelectricity, which has a strange effect, the photoelectric effect.
Scientific instrument test: Jade also has this special "photoelectric effect", in the process of slightly exerting pressure, cutting and polishing in the finishing process will make the dumping kind of effect focusing energy storage to form an "electromagnetic field", and radiate a kind of Can be absorbed by the body's far-infrared waves, which in turn induced a strong **** vibration of water molecules in the body's cells, making a slight massage to improve the microcirculation system, thus accelerating the body's blood circulation and metabolism to enhance the revitalization of cellular tissues and regulate the precise operation of meridians and qi and blood, to enhance the rapid response to improve the body's immune function. Therefore, a Chinese medicine practitioner said: "Some diseases can not be cured by medicine, but often wear jade can cure the disease", the reason lies here.
l, should first establish a concept of A goods. To correctly distinguish between B goods, C goods, the first thing to know what is A goods. At present, the market jadeite A goods, B goods, C goods mixed, it is difficult to distinguish between true and false. In this case, how can a beginner accurately start A goods? The author believes that we should go to some of the more reputable, larger storefront market or jewelry store. It is best to go to see some of the celebrities or master appraisers have issued certificates of appraisal of jadeite goods. Such as Shenzhen in Hong Kong International Jewelry Exchange in the jadeite goods where the grade of some of the higher, there are Hong Kong Gemstone Appraisal issued by the certificate of authenticity. Hands on such a jade on the correctness of the intuitive understanding of the A goods, its insurance factor is naturally higher.
2, the use of scientific methodology, follow the correct identification procedures. Get a piece of jade, the first thing to do is to determine the authenticity of its work, to see whether it is Burma Cui or Gui Cui or Malay jade, and then do A goods, B goods, C goods discrimination. In the authenticity process, the main use of specific gravity method, refractive index method, felt structure observation method to distinguish between them. Because, there is no jade with felt structure and green color whose density and refractive index are the same as that of Burmese Jadeite. The author has had a deep lesson in this regard. That is in the jadeite collection of the early days, when the author simply do not understand what is jadeite, the green jade are considered to be Burma Jade. By chance, I met a very famous gemstone appraiser (the only certified gemstone appraiser in the region at that time). Whenever I get a piece of green jade to go to the humble advice, and every time I can get the teacher's praise. As time went by, my collection grew, but my questions grew bigger and bigger. Why so many "jadeite" fine goods have come to my hands! Since this kind of thing is worth a lot of money how can there be so many? With these questions, I began to buy books to consult information. At the same time also bought back the balance, a bromine nai and other detection tools, and often in and out of some large jewelry stores, trying to find ways to get their hands on a certificate of jadeite A goods. In these large jewelry stores, I recognized the felt structure of jadeite. Using these testing tools, I understood what is the real Burmese Jadeite. However, what came along with it was the total destruction of my own collection. This incident touched me a lot. Therefore, to engage in the collection to rely on their own, to worship the teacher to ask for advice is necessary, but the most important thing is to rely on their own enlightenment, rich knowledge and practical experience, rely on rigorous reasoning and scientific methodology.
3, consulting "experts" to believe in "experts", but not superstitious "experts". Ancient Greek philosopher Aristotle said a famous saying "I love my teacher, I love the truth". However, in the pursuit of truth, is to pay a price. As mentioned earlier, in this regard, the author has had a painful experience. Of course, the first time into the collection of the way, learn from a teacher, please "expert" palm eyes is very common. But I do not know that "experts" is also a mixture of good and bad, there is no lack of indiscriminate people. And "experts" are not omnipotent people, only in a certain field of study. Otherwise, it is not called "expert", called "the whole family". To the "experts" of the conclusion, we must have a correct attitude, to believe but not superstitious, not to mention blindly follow. To more "experts" to mention a few why? Answer logical and reasonable to listen to, or else discarded. In the antique world, "experts" hit the eye, out of jokes happen from time to time, the author had an occasional full of green jadeite pendant (see chart), after the test that is jadeite A goods, so take it to teach the local antique "experts". "Experts" look at it threw over a sentence "fake"! Asked why! Answer said "do not feel right, like this thing if it is the real thing is not possible to pass to your hands". Asked after "you say is fake, that is B goods or C goods"? Answer said "what B goods C goods, fake is fake. I was stunned? After knowing that the person is engaged in porcelain collection, only know the skin of emerald. Therefore, when asked to teach experts, one should have a number in mind, to ask the industry experts. For those "half-bottle vinegar", and not modest two knife "expert" to respect far away, there is no need to let him comment on your collection, blasphemy your mind. As a result of the work relationship, I have taken this thing traveled far and wide, to teach many "experts". I remember once in the north of a metropolis, introduced by someone to meet a professor of a mining institute "expert", the "expert" took this thing with a flashlight, magnifying glass looked at half a day, said: "like jade! ". I listened to the cool half, as the saying goes, "a connoisseur on the hand, will know there is no", your old man stone research a lifetime, the conclusion is not a little too cautious. There is a time I came to the south of a large city, the city is engaged in jewelry and diamond ring quality month free appraisal activities. The author will be sent to a young jadeite twenty-something "expert" hands, in order to have a "pioneering" conclusion. Who knows that the "expert" to the emerald in the hands of a paw, said: "stained quartzite". I was almost out of breath, this can be really "grass and bamboo life" ah. A bit of mineralogy people know that quartzite and jadeite specific gravity difference is large, as aluminum, copper is to close your eyes with a hand paw can also be identified, not to mention that you also open two "expert" eyes.
In order to confirm their own conclusions, the author went to great lengths, after finally in Shenzhen, China and Hong Kong International Jewelry Exchange to see the real jade appreciation master Ouyang Qiumei teacher, and by the Hong Kong Gemological Appraisal issued a certificate of appraisal. Conclusion is "hereby certify that the photo shows the jadeite for natural Myanmar jadeite (A)". The significance of this matter to the author is significant. On the surface, the appraisal is just an insignificant jadeite, but essentially it is the author's beliefs, methods and efforts to identify the results of a. The author believes that in the jadeite collection and even in the collection of jadeite, the results of the appraisal of the author's beliefs. I think in the jade collection and even the whole art collection process, the expert's review to do more specific analysis, including their expertise, emotional attitude and said every word. Such as "experts" said your jade is C goods, you have to focus on analyzing the jade surface cracks and cracks in whether there is dye. In addition, if a piece of jadeite under magnification, its surface has many yellow-brown spots, then, no matter what others say it is the possibility of B goods are unlikely, the reason is very simple, in the production of B goods rinsing, glue injection two processes are not allowed to exist in these impurities.
In summary, as a jadeite collection enthusiasts, in the jadeite collection process and even the entire art collection process, humbly to the "experts" is very necessary, but can not be superstitious and more can not blindly follow; to strive to enrich their professional knowledge, the courage to practice, set up a belief in respect for the facts, believe in the facts!
Jadeite A, B, C goods
Jadeite A goods, for pure natural jadeite. Only after the traditional mild surface acid or surface pier wax treatment, the structure of its emerald to corrosion and destruction.
Jade B goods, the state promulgated jewelry and jade standards, optimized for the processing of jadeite, after the acid dip bleaching, pier wax treatment of jadeite. According to the strength of the acid immersion bleaching, can also be divided into strong corrosion and weak corrosion of two kinds of strong corrosion optimization of emerald equivalent to the market known as no gum B goods. Its internal destruction to a large extent.
Gum-filled treatment of jadeite in the process, after a strong acid corrosion bleaching, to save the best inferior treatment, the internal structure of its emerald was seriously damaged, and then injected into the increased penetration of cemented gelatinous polymers to fill the so-called gum-filled goods. Regardless of optimization jadeite or gum-filled treatment of jadeite, in fact, should be designated as destructive treatment of jadeite that is B goods. The weak corrosion of jade, because of its internal destructiveness is not great, should be called optimization of jade.
Gum-filled plus color treatment of jadeite and no gum power day color treatment of jadeite, through the acid-soaked bleaching injection or not injected with gum, and add dye jadeite jewelry called B + C goods.
The C goods of jadeite, for the dyeing of jadeite. Regardless of the acid-bleached or not, glue-filled or not, where artificial coloring of the jade called C goods.
Currently the new trend in the treatment of emerald, strong acid treatment, not filled with gum, but filled with wax. Full of wax for optimization, full of gum for processing (B goods), so drilling a hole in the national law.
In addition, a long time ago, there is water glass (silica) filled with emerald, the effect is very good, no one knows yet. There are also nanoscale aluminum, silicon material filled with jadeite, are known as high-grade B goods.
Spring with color
Spring refers to purple jadeite. Purple jadeite is also known as violet. Color represents pure green. Spring with color refers to a piece of jadeite or a piece of jadeite jewelry with purple and green. Currently spring with color jade material has been very rare. In 1991~1992 out of the high grade kai su raw materials, see have violet, have green, water good raw materials, but half a year to dig out. Good spring with color jadeite value is very high.
Five-color jade
Five-color jade is in a piece of jadeite raw materials or in jadeite jewelry with more than four colors called five-color jade. Such as green, purple, blue, white, etc., in the evaluation, in addition to other conditions, mainly to see how much green and water for the main conditions. If green accounted for a large proportion and good water, this colorful jade is very valuable.
Eight-three jade
Eight-three jade refers to the emergence of a new factory jadeite in 1983 in Myanmar jadeite origin. Is a kind of water dry, bottom poor, structure loose crystallization coarse a kind of lowest grade brick material. All used to do jadeite B goods or stained jadeite, if not artificially processed is useless jadeite raw materials, it is a variety of jadeite, its mineral composition and physical optics of the three elements are the same as normal jadeite. Because of its loose structure, coarse crystallization, it is easy to change the acid treatment of its translucency, and easy to fill the gum color. After treatment, the water is better, waste for use, low price, should be treated correctly eight three jade.
Three elements of the physics of jadeite
All the world's precious stones, have data that can explain their identity, these data lock their identity, which is their physics of the three elements. All the precious stones in the world rarely have the same three elements of physics. These are hardness, specific gravity (density) and refractive index. Jadeite hardness of 6.5 ~ 7, specific gravity (density) of 333, refractive index of 1.66. followed by toughness, resolution, fracture, color, dispersion, transparency, luster, luminescence and other characteristics to distinguish.
Tie Long Sheng
Mainly refers to the complex as the chromogenic element of the positive green, dense structure, head of water is poor a kind of jadeite, by the chromium-rich stibnite mineral aggregate composition. Minerals are mainly stibnite accounted for more than 95%, followed by chromium, town, calcium, iron and so on. Make degree, specific gravity, refractive index are the same with jadeite, actually a variety of jadeite. When its specific gravity, hardness and refractive index and jadeite different at the same time, indicating that the other minerals within the increase in content, is not a variety of jadeite. In ancient times, it has been used to make thin jewelry, very beautiful.
Oil green
Oil green is a kind of fine texture, translucent dark as oil jadeite. There are two kinds, one for the dark blue tone, the water is very good, light observation for blue-gray tone, without green tone. The second for the blue-green tone, light for green tone, water is good. By analyzing the former oil green jadeite does not contain chromium and contains more than 1% of the divalent iron ions. The latter oil green jadeite contains traces of chromium and iron.
In addition, there is a kind of oil green "Jadeite", it is the same tone with the previous oil green for the dark green water, but the hardness is only 5.5 ~ 6, specific gravity, refractive index and jadeite difference is very big, after researching the main green pyroxene, the second for the stibnite, does not contain chromium, but iron, should be called green pyroxene jade or green pyroxene Jadeite.
Jadeite dragon species or God species
Dragon species or God species refers to the jadeite jadeite green completely dissolved in the "ground" within the green uniformity, color "ground" with the coordination. Color tone is not strong or light, do not see the color root. From the emerald "ground" within the reveal the gorgeous beauty of the bright, is the highest quality varieties of emerald.
