And nephrite seed material from different areas of identification and characteristics of
a jade in Xinjiang Hotan Jade Dragon Kashgar River or the production of skin Aberdeen jade jade mountain water upstream of the output of fine texture, moist, cloud patterns in the short and dense flocculent , good toughness enough oily, translucent feel gravity: about 3.0, Hardness :6-6.5 degrees. carved on the ground when the machine is not easy to crack. all earners out of the surface of the moist jade polished clean, polished surface we called and nephrite due, the relationship between the different crystal structure, Russia is full of jade out of the flat polished hollow bark pit polished surface. expert called the Russian jade polished surface.
two Russian Bear Lake added sugar Yushan Bai material: filled with a clear pattern in the flocculent cloud clumps, loose structure, density is relatively small. cottony clouds mixed with freezing crab claw pattern texture, its color stiff white, mostly oil almost. carved on the ground when the machine easy to play, easy to crack, especially Fine grinding surface of the finished product will be a mass of a group of bark depression, experts known as the Russian jade polished surface gravity: about 2.95. 俄罗斯布利亚 special structure near Aberdeen and nephrite material of high density, fine structure, short cloud flocculation like structure.
three Qinghai jade: found in the northwestern margin of the Qaidam Basin, Qinghai Golmud, Qilian County in Qinghai jade water weight, high permeability, oil poor, small point-like cloud of loose floc structure is that it typical of fiber crystal structure changes, blankets structure, subhedral medium-grained mosaic structure, the residual crystal structure Jade organization which can often be seen on both sides of jade than a more transparent organization, also known as Jade tendons waterline. set play Over time the color will be gray, dark, carved on the machine when grinding brittle, easy to crack. finished with frosted glass feeling. because of its low price, it is full of white jade market. hardness of 4-6 degrees, the proportion of 2.9 the following crater of Qinghai Jade is better Color: white, white, light green, green, brown.
four. Qiemo Jade: point-like, loose, rugged cloud floc structure is often accompanied by stiff black point or white point black spots chrome spinel, white stiff point of dolomite. Qiemo jade from the pack slurry oil is good to do most of the main antique pieces to block mountain material degree.
V. Yu Tian: There are mountains and jade Aberdeen material, and a new pit crater. cottony clouds or filaments elongated strip texture, because Oda is the new Jade Mountain pit material, the use of explosives in mining, when the breaking so often over the new pit jade split on blame, and the hardness and Tian and texture is not dense, oily good color good MOISTURE.
six. Liaoning Xiuyan River mill Jade: Jade is a river Kengzi, cottony clouds thick and messy texture, color, mostly yellow, blue or green and entrainment of the main stone of heavy stiff spots and skin. often wallets of meat, meat folder skin condition. because of its rich colors, some blue green yellow or blue often part of the tone,Timberland 6 Inch, much like jade unearthed Qin is not affected by the window part of the true nature of jade. blending some tend to coffee, yellowish brown, cinnamon yellow color tone, much like jade unearthed part of the soil by the Qin Qin color, while some spots are often stiff mottled brown opaque Youyi yellowish brown, brown tone-based, much like the first by the lime jade unearthed Qin Qin after the other longer feel so much for the river wear jade antique pieces.
identification
a white filling Introduction
In China ancient times, people Chong Shangyu stone, jade is often used to describe the quality of people, with jade is a status symbol, as early as 5,000 years ago, began using jade palace nobility Subsequently the various dynasties, jade, while having its own unique meaning or shape, but the development of jade has never stopped, and recorded in the history of the development and history play an important role can be said that the history of ancient Chinese jade, and is one of China's development history.
Ancient China demanding of jade, not all of the mineral crystals can serve as a collection of jade, look at the history of the Chinese nation for thousands of years, so nothing more than a few jade: soft jade, Jade, Dushan jade, turquoise, which Several features of Jade is the most typical warm, gentle symbol of a gentleman of which the most common soft jade, the highest status, while the soft jade in China's Xinjiang Hotan County Youyi produced for the top grade.
nephrite divided according to their color several varieties: white, jade (green belt or green belt, black and cyan, gray-green), green jade, jasper (different brightness of the green), topaz, black jade, candy jade (blood-red, red Tong red, purple, brown and red ), jade and other flowers, which the white best.
and white according to the different degrees of white there are different terminologies, such as suet white, pear white, snow white, ivory, bone fish, white, brown white, chicken bone white, white as tallow which treasures of the best.
However, the real nephrite jade is very little suet, now the Palace Museum in Beijing and Taipei Palace Museum collection in soft jade, sheep few fat jade so, China's market, or even the whole Asian people on the market, price is almost suet jade, white jade to stimulate the price soared.
white market price rises there is an important reason that is, fans are very preferred Hotan jade nephrite, more desire and Tianbai Yu.
However, Hotan, Xinjiang, as in ancient China can be said that only a soft jade origin, after thousands of years of exploitation of mining, its production has been great as In the past, high-quality jade, jade, especially suet and even fewer.
Therefore, in order to meet growing market demand in recent years, Qinghai, China and Russia, the emergence of more and more white on the market, Russia in particular, white, white jade markets now account for more than 60%.
study found that Russia and China's Xinjiang white jade is slightly different in structure, particle size greater white Russia, the majority of grains in the 0.01 ~ 1mm between the granular structure of the overall presentation fiber, Xinjiang extremely dense white structure, mainly woven fiber structure, but this gem is difficult to observe under the microscope,Timberland Roll Top, can see only a small number of interwoven filaments from the gloss and transparency, the Russian white transparency, gloss and strong, usually glass, gloss, transparency and Tianbai Yu relatively low, oil sheen gloss is soft.
short, and Tian Baiyu from all nature, it is more rounded with Chinese jade culture requirements, but in the gem laboratory, these differences do not make much sense, we identify the origin is difficult to find strong evidence, including such large as DEXRF other instruments are not meaningless, but people like soft jade, or that traditional cultural values ??that tend to jade and nephrite.
made us these so-called gemologists Incredibly, in the soft jade industry, a number of hand, it is able to distinguish Wada material, which is the Russian material. Of course, the number of its accuracy can not be verified, but, from the number of letters from those who, we know that these people can only realize this unspeakable experience or identification standard is, in fact, represents the identification of certain aspects of the industry grading standards authority.
However, this standard is really difficult to explain in words, the formation of such authority is not one two years can be formed, for many people, this experience is gained almost cost his life energy, so the industry is not inherent in a large number of skilled technical people, which is provide loopholes.
two white filling process
general Russian white imitation or bogus and Tianbai Yu, similar to Thailand to get Burmese ruby ??ruby ??posing or pretending to take the Sri Lankan sapphire Kashmir sapphire, but filling treatment of Russian white posing and Tian Baiyu not the case, it is more like poor Jade bleached, after filling (ie, B jade) high-grade jade posing even say that they approach the process exactly the same only because white The structure is more compact, the extent of corrosion by acids smaller, so when the bleached white more difficult, more difficult time filling some of it.
In addition, at present, filling processing is no longer rampant pretending to Jade high-grade jade a (except for some of the tourism market), as its technology matures, open, and the various testing laboratories already have mastered the difference between it and the natural method of jade, buyers have become increasingly sophisticated, so that now of B jade is a kind of bogus products as they say, might as well say that a variety of jade is nothing, but in the sales process after the time indicated it wants to.
and the white filling treatment is different, people have been Russia believes that the white material, Qinghai white jade and nephrite than the low grade rather than the original accept them, and now after the filling process, if the purchase had not been informed, the purchaser must have felt cheated.
again that is, the current approach and process white is still high trade secrets, and even the behavior of white and filling process are known, so that almost all buyers do not know white will be processed, they do not think the hands of .
three white filling process identification
from the senses, and particularly the color and transparency, and Tian Baiyu more like animal fat, especially the large intestine of sheep fat, natural sense of the Russian white is ice , while the white filling treatment, it felt more like snow, especially as the snow was hard pressed by hand.
refractive index (point measure) are mostly 1.60 to 1.62, or 1.60 ~ 1.61 are basically
identification of the polarizing microscope, there is little sense, but according to statistics, Russia cut light material weaker.
under ultraviolet light, and Tianbai Yu and Russian material showed white basically inert, and some white filling In the long wave medium under white fluorescent.
microscope, the top light sources, and Tian Baiyu surface is very smooth, light transmission to the internal uniform, that is, and Tian Baiyu dense homogeneous structure; and white Russian material often see the grain surface mounted to distinguish between crystal boundaries, and occasionally you can see the face of a crystal orientation of light reflection. filled with white surface roughness, potholes uneven phenomenon, similar to the frosted glass seen under the microscope, and intaglio parts of the flat surface, you can see a similar phenomenon nephrite uneven fracture, and occasionally can be seen more obvious pits, pits the luster is relatively weak, at different filling jade, nephrite filling ditches could barely see the cut lines, This shows that even a relatively coarse structure filling nephrite, jade is still relatively compact and much more. In addition, some filled with soft light brown and yellow jade, can be found under the microscope, the more internal to the jade-depth, the deeper the color .
end with a strong light irradiation or light irradiation observed with optical internal jade, often seen cotton wool-like inclusions, occasionally black inclusions, while the Russian white filling material and almost no cotton wool-like inclusions, but many See some similar cicada wings, and some similar veil interwoven structure. impossible to find a black bag filled with white body.
the most effective and most accurate way to identify the infrared spectrometer.
from the skin color ,cheap timberland sale, see the sweat pores and nephrite seed material
end early this year,cheap uggs, Xinjiang Hetian sudden increase in the price of seed material, a few months, prices have gone up several times, and even sold price of 1,000 yuan per gram, better price per gram of seed material in more than 100 yuan. price spikes that fake manufacturers excited, intensified, rampant fakes on the market to the point of unbridled and now occasionally seen on the market so-called seed Xinjiang Hetian jade material, even the real thing not to one per cent, while counterfeiters means superb, insiders also Lianhu fooled without knowing it.
but in any case of fraud, there are always people to see through the place, such as skin color and roll from the expected to identify the start, when a glimpse of twelve.
a live skin. really the seed material in the river thousands of years of erosion by sharpening, naturally subject to the Qin, it will place in the texture of soft pine Qinru color, in a split sub- where depth texture. This is a natural skin color, skin called live it the color of jade immersion within the layered, natural transition, the feeling of the skin and meat is the same. skin color should be for the shallow depth, The color should be on the cracks from shallow to deep. In fact, good skin jade is not long, that is scattered or in small crack house.
Second, the dead skin. fake leather posing first seed material the second is to meet the love of a variety of skin colors like jade tendency to fake leather is top secret, but is said to be stained carpet with a dye, with a sponge absorbing enough of the dye, the jade on the inside, and then try to penetrate. false skin color and the seeds are mostly raw materials in the natural environment Yu Qin of metal salts by the same things, mostly purplish red skin. This paper floating on the surface, the color is too bright, no transition of the natural layering, and dry, not moist . fraud skin jade loose parts in place, called the dead skin. This skin color with a hot water it is easy to fade fades.
three roll material on the market more common materials posing as seed material roll . roll material is expected to even the mountains of Qinghai material, the Russian material,Timberland 6 Inch, waste material Jade pieces, roll into the drum machine grinding, ground into oval, much like the seed material, and then dyed imitation leather posing. fraud are even expected to open into a small chunk of mountain polished material. This market is flooded with fake seed material, fooled a lot of people, I myself have repeatedly fooled. roll material prices are not high, usually about $ 30 you can buy a . This alone, can not conclude that the seed material. If the seed material, the same size, are afraid of a few hundred dollars to several thousand dollars.
Fourth, the sweat pores. sweat pores here is a generation of word. whether the sweat pores, true and false identification of seed material is really trick. The real seed material, no matter how fine, it's surface, there will be numerous thin thick holes, much like human skin, the sweat pores. This in natural state to form the surface of the phenomenon, by no means out of the manual can be forged in times magnifying glass, you can clearly see. with sweat pores to identify true and false seed material is very effective because the rolling mill roll material off above Scar, a Road scratches, but not the natural state of the .

on Jasper Jasper is a tremolite jade, serpentine is intrusive mafic volcanic rock formed after the other nephrite, and worldwide in addition to the soft jade produced in the Kunlun Mountains, the other as North America, Oceania, mostly produced jasper, the color was different levels of green. Manas Manas jade produced in the southern Tianshan Mountains, Xinjiang, Tian Shan, also known as jasper, green, dark green, uneven tone and with gray.
Manas jasper ore containing ultramafic rock to the water distribution in Anjihai River. Ga for the northern Tianshan Ha Bier
hillside to the north wing of the late Paleozoic forearc mm trench with ophiolite, in the northern Tianshan belt of ultramafic rocks of the eastern section. jade mine and mine has been discovered 2.6, of which table to yellow jasper mine as the most important.
jasper original rock can be divided into two types: one for clinopyroxene peridotite, peridotite into serpentine rock; Another change for the pyroxenite to the serpentinite the former common form of Jasper uniform distribution of chromium spinel, the latter because of serpentinized Usually there is no chrome spinel is not completely by the formation of the two original rock jasper, the quality of the former than the latter. Canada jasper and jade that the Manas is the former.
jasper ore bodies several meters long to the general ten meters wide and tens of centimeters to one meter, extending one to five meters. the middle class to the level of quality Dart, and the edge of poor quality. orebody outsourcing layer of chlorite and tremolite mineral composition of the shell. grayish green or gray. jade green lump ore, oil sheen, slightly transparent to translucent, hard and tough, mainly mineral felt like tremolite, accounting 75m90%.
small nephrite tremolite, and more merged into the pinna , woven into a carpet-like, followed by the slightly larger needle-like tremolite, accounting 5m15%, non-aligned in between the felt-like tremolite in addition to more impurities.
Manas is in the Qing Dynasty jade mine have known. prohibit mining over the years the mine mouth has been unknown .1973, Beijing jade plant based on old British artist Mo Manas City acquired a piece of jasper, after a few months to find Jasper visited the mine, to see the Qianlong period Caiyu sites in the year on the establishment of a jade mine Manas .1975, at the Manas River Red pit mining of a 750 kg large jade, carved by the Yangzhou jade plant into a national treasure,
In addition, the Kunlun Mountains region also produced jasper, green, and Hetian jade color with different surface oxidation due to Hetian jade black, seeds are often sold as black jade, which is the need careful identification.
In this paper, reference and Taiwan, the Earth Xinjiang People's Publishing House co-published The felt-like woven structure, mineral particles are very small, typically around 0.001mm, is reflected in the appearance: fine texture, fine-grained porphyritic crystal structure of nephrite variable output proportion of large grain size heterogeneity, which in appearance is not enough detail of the performance of texture, slightly shiny porcelain of.
3 in the Russian compound is also a considerable part of the can not be generalized, Russian nephrite in the top grade in terms of br> Hotan and the difference between the Kunlun jade
to produce , dense. because it is composed of tiny interwoven fibers, so excellent toughness, unbreakable, light-chun, moisture, often has a sense of grease or oil sheen gloss of glass, gives a warm feeling.
and Tian general micro- transparency, hardness is about 6.5, a refractive index of 1.61-1.62, a density of 3.0g/cm3 about the color white, gray, yellow, green, yellow-green, gray-green, dark green, dark green, black, etc. and by Tian varieties can be divided into suet white jade, jade, jade, green jade, jasper (specifically refers to the soft jade green), black jade, topaz, candy jade, jade flowers, Jinshan Yu, etc. suet fine texture, glossy and strong, white such as suet, called and acid intrusive rocks in the contact zone. with some symbiotic and nephrite mines, such as Al Masi Kunlun jade, and nephrite veins veins appear in the edge, so-called a fellow of the twin sisters of milk, according to experts, the Kunlun and nephrite jade in the material composition, occurrence, structure, basically the same structural characteristics. only in the output characteristics, structure, properties and some aspects with a slight difference between nephrite.
Kunlun jade was crystal-like pattern and braided lines shape, texture and delicate unique, beautiful and rich in color, pattern and diverse, soft material easily understood attack. Kunlun jade different types of white, gray jade, jade, green vaginal discharge, white sugar packets, etc., to crystal jade rounded, innocence, no cracks, impurities for the top grade. carving, so the green part of the whole carving patterns presented in the right place, such as the head or foot, saw people feel beautiful. , in carved objects, the Kunlun jade carved through a variety of techniques, the made works such as pen, flower holder, paperweight, inks and color stone mosaic bowl seat screens sleek, elegant, so that viewers and buyers love. Kunlun jade in white in the past jewelry market downturn a few years prices have been rising in the face of adversity, four years rose to 300-500%, with high investment value to the collection.
Hetian in Xinjiang and the hollowing out of the old veins largely because Kunlun jade and nephrite are very similar, many people began to fight the idea of ??the Kunlun jade. Kunlun jade, but not many old mines, new jade mine is obviously not keep up with the old mine, many businessmen began to dry up shoddy , deceptive acts that the experts recommend that consumers purchase Kunlun jade, be sure to pay attention to jade, jade and jade of the Kunlun jade jade must be clear, not gray is not evil without variegated; jade jade of thin and uniform profit, pure and no complex, no matter what color, texture, nourish the more the better, the more detailed the more significant moisture. Kunlun jade as ornaments, suitable for a variety of personalities, ages wear were bought to the attention of texture, color, gloss, block and other aspects.
and nephrite jade is designed to identify
refers to the tremolite-based soft jade (and nephrite), dominated by the formation of other mineral jade, must known for its white and not white. Some operators will not be called white white white jade, the objective to mislead the consumer, deliberately not called white white white jade, impurities, and this is criminal behavior. Some sellers on the Internet often have to produce a white Tanglin Xinjiang jade deliberately called species, he did not say and nephrite - white jade in the jade market, often referred to as two white jade white.
First Class quartzite jade, white color, finer texture, appearance like white, past the so-called stronger showing than the white sheen of glass, in the absence of detection of the instrument case, you can differentiate accordingly.
1. Water Stone: This is the main component of quartzite jade, its hardness, but brittle, easy to break The internal structure is granular. color was pale color, gloss looks more dry.
2. water white: Jade is a kind of Nanyang, Henan, is plagioclase, glass, gloss, and some very thoroughly, but also semi- through the hands weigh lighter float, the overall look white in the black hair (with gray or blue and white jade green smoke completely different), but a closer look Shiyou not find the white, spread on the common.
3. Tanglin jade: jade green Tanglin common, there are blue, red, white, producing more, Xinjiang produced Tanglin jade is white, is a quartzite, granular structure, strong luster, slightly lighter weight, are also commonly used to Tanglin jade jade jewelry, jade bracelets Tanglin market price of about 100-150 yuan, a small pendant around 30-50 dollars, there are many famous Tanglin Jade Stones and the Buddhist Goddess of Mercy, and sometimes green is often used to take full Tanglin jade green jade. similar to several other jade and white jade jewelry little to do, because the value is too low, only used for large-scale sculpture pieces.
Second, the calcite class jade, white jade similar appearance, such as the market so-called symbol -like luster, the internal structure of water, linear, stripe-like.
2. Afghanistan and white: a very delicate matter in Afghanistan Baiyu Yu uniform, shiny oily, invisible flower jade, jade is often used to impersonate or upper suet jade, identify the method is very simple, just hard with a fingernail scratch that, if the skin can be scraped a little white, not white. In addition there is a serpentine jade that Jade, Xiuyan produced in Liaoning Province County, Jade production of large, low hardness, easy to break, the price is lower. general transparency is relatively high, mainly in the green water is mainly used to impersonate and Tian Qing, jade, jade, yellow Jade is more common, mainly posing Topaz , Jade also has white, cotton and jade have now also found a large number of Xinjiang serpentine jade because of Jade hardness less than 5, so the program does not move the glass.
particular note is that some old goods market, often posing as white emulsion or jade glass, glass products can often be seen round the bubble size variable as long as you can see a bubble is certainly not white, but some glass and no bubbles, so no bubbles are may not be the real thing. to be sure to buy the real thing, or should we look for jade jewelry testing department to test, because some white jade resembles a white, not strictly to detect, difficult to make accurate judgments.
and nephrite is very high hardness, toughness is also very strong, and nephrite can the glass, but no damage itself for other jade, only quartzite jade class itself can be the glass and no damage, while the water stone is often used to Need for posing and nephrite jade suet, suet white jade is sheep fat, water, stone is a pale color; suet jade is oil sheen, the more water stone dry, good gloss.
identify and Tian Baiyu from the appearance of three side, and the naked eye can see fine Tianbai Yu Xiaoyun sheet, cloudy jade flower structure, which is specific to structural features and Tian Baiyu; and Tian Baiyu luster is very moist, not the kind of strong glass, gloss, that is and Tian Baiyu surface reflection of light is not very strong, which is due to the surface and Tianbai Yu has a very small bump,cheap timberland boots, similar to frosted glass, with 10-20 times the magnifying glass you can see, sometimes also see the left hand polished along the lines of a certain direction; observe the incised lines, and Tian Baiyu toughness as strong, in time, not easy to play collapse, incised lines on both sides of the mouth is not easy since the collapse, although the high hardness of quartzite jade class, but poor toughness , brittle strength, incised lines easily from chipping. It is for this reason, many types of jade are quartzite with high pressure out of the mold, not hand-carved signs.
Tian identification (for novice research)
China and nephrite have been for thousands of years, it is recognized worldwide as the Let us clearly understand and Tian, ??the following to introduce a few simple ways to identify and Tian:
First, tell us about some common counterfeit goods posing and nephrite:
1. jade marble the color of white, gloss is a waxy luster, the internal structure of water linear, stripe-like.
2. the water of this jade stone is the main component of quartzite, its hardness, but brittle, easy to break. The internal structure is granular. color was pale color, gloss looks more dry.
3. Jade is produced in the former county of Liaoning Province Xiu is another Chinese jade. Xiuyu production of large, low hardness, easy to break , second only in value and Tian its internal structure was the cloud sheet. the main green, mainly used to impersonate and Tian Qing white.
4. emulsified glass, which is a pure fake, is modeled on artificial and Tian synthetic glass and it does not clear structure, with the naked eye can see air bubbles inside.
Second, tell us about the methods to identify and Tian:
and nephrite is very high hardness, toughness strong . and Tian can the glass, but no damage itself for other jade, the stone can be classified only in the water glass and no damage itself while the water used to impersonate rock and nephrite jade Need suet, suet white jade is sheep fat , water, stone is pale color; suet jade is oil sheen, the more water stone dry, good gloss. Hetian structure was not cotton wool in the glass case, to carefully distinguish between the colors and their internal structure, do more .
Finally, give you some maintenance tips jade:
jade afraid of fire, fear of shock (bump), fear of fishy oil for Hetian jade, the best personal wear, because of its internal micro-mineral element is a living, can be absorbed by the body, the human health benefits, while the human body can keep the sweat out of jade, and nephrite gloss to make better and better, is the so-called . Jade is also very simple cleaning with a toothbrush and water can be cleaned, should not put chemicals, it will destroy the luster of jade.
On the Qinghai Qinghai Nephrite Nephrite
output in the nineties Jade has been a major event on the market ...... Since 1994, the Xinjiang on the market a lot of soft jade produced in Qinghai products because of its traditional and nephrite have some different characteristics, and for volume of large, inexpensive, and sometimes on the market and cause greater impact Tian Author according to data collected over the years, the Qinghai nephrite and the appearance of the main characteristics of commercial varieties, petrology mineralogical characteristics of the system of research, with traditional varieties were compared, and Tian, ??the findings will now be available to the industry reference.
one origin introduced soft jade produced in Qinghai Golmud City, Qinghai Province, southwest of the Qinghai-Tibet highway a hundred miles along the hills of the plateau region has been mined ore about three points the local high altitude, although the relative height difference, but not, traffic is convenient. out of the real estate to mining jade mountain based materials, a small amount of mountain water (Gobi) material, no sub-material. is a lot of output into the eastern edge of the Kunlun Mountains in Qinghai Province part of the west of Xinjiang Ruoqiang border about 300 km, and Qiemo, Ruoqiang and other property out of Hetian jade background in geological formations is closely linked to .
Second, the major commercial species and the appearance of the soft jade in the output characteristics of Qinghai early, there are white Kunlun, Kunlun jade, jade Golmud, Qinghai jade (emerald green variety) and other non-standard name based on national standards name , ash - ash purple varieties of products in traditional and nephrite are we in rare or not seen.
now all varieties and characteristics are as follows:
Qinghai nephrite jade mm main species, but also the largest production varieties, the industry is sometimes used is called ; quality. the industry according to their different appearance of the image features described as: milk white, permeable white, white pear, white rice and other varieties. Qinghai white uniform texture, nourish, block degree, is a superior good material, but its partial transparency high, solemn feeling inadequate, particularly after doing thin buoyant.
mm for the light gray green white green - blue gray, yellow gray, cool and elegant color, translucent, uniformly fine texture. transparency was greater than the white and Tian Qing, head enough, good uniformity, popular with traders. often aptly called: White blue, cyan, white, duck egg blue and so on.
sapphire mm schungite - dark green color than the stuffy dark, translucent, and texture often superior to, and Tian Qingyu, head full of good, suitable for production of medium and large get ornaments, utensils. so thin turn positive after the tone, dignified and elegant, sonorous rhyme for quality jade.
smoke sapphire mm light - medium gray purple to smoke gray, smoke gray slightly gray. translucent, delicate texture, moisture, it was called violet, pale pinkish purple jade, Wu Qing Yu, etc. In rare traditional varieties and nephrite. because of the color characteristics significantly, can be said that Qinghai nephrite a sign of varieties which were independent of thin-bedded varieties of output, but also ...
