China since ancient times

 The ancients as the jade as something precious, as a treasure to wear ornaments. Ancient medical books called That suck with jade, with the help of saliva and its synergies, use, but also for health fitness. Since ancient times, the emperor of the Korean health concubines separated from jade, and Huizong Yucheng addicted addiction, Yang Yu-town with summer.

health jade mechanism has been confirmed by modern science. According to chemical analysis, jade beneficial to human body contains many trace elements, such as zinc, magnesium, iron, copper, selenium,UGG boots, chromium, manganese, cobalt, wearing jade can trace elements absorbed by human skin, activate cells and tissues, enhance the human body immune function. And therefore, traditional Chinese medicine said, If the positive long-term wear jade bracelet massage, passive addition to blurred vision not only of the disease, but also build strength, raise the spirit.

Yufu and Yutian experts say:

[white] are calm and soothe the nerves of the power.

[Sapphire] to avoid the evil, energetic people.

[Xiuyan] change the body functions and improve the natural healing ability.

[Emerald] respiratory system can ease the pain, can help people overcome depression.

[jade] Run cardiopulmonary, Qing Wei Huo, eyesight beauty.

[Onyx] heat eyesight.

[old jade] detoxify, clear yellow water, the solution Rat sores, Yin Wu to be, Zhitan fans panic and malnutrition sores.

jade not only beautify people's lives, the yardsticks, and illnesses and security and peace. Their products directly to health care are: jade pillow, jade mats, fitness ball, massage, walking stick, jade combs, on the human body has the beauty, calm and soothe the nerves of the efficacy, long-term use, will make you filled with energy and longevity.

[jade formation] The formation conditions of jade is very special and complex. Most of them tens of kilometers from the depths of underground magma melting temperature, the temperature of the slurry from the ground rushed to the Earth's surface along the cracks after cooling into solid rock. In this process, only certain elements slowly crystallized into a hard, jade, or precious stones, and their formation time is very far away from us.

Jade has can be divided by the formation of several important stages as follows:

one, dolomite sedimentary stage

in the late Mesoproterozoic (about ten million years ago), ancient land in the southern margin of Tarim, which is today the northern margin of the Kunlun Mountains location, once a shallow sea area, where a large number of carbonate salt deposit, which contains magnesium in the dolomite as the main material source of jade.

II Jade metamorphic dolomite areas

in the late Proterozoic Sinian, caused by the movement of the Tarim region folds strong fault activity, which eventually formed the Tarim continent. A wide range of regional metamorphism in metamorphic dolomite to dolomite marble. Since then, the region's land mass uplift, and has become one of the first exposed surface of the land, on which there is no layer of sediment covering the original.

three stages of dolomite metasomatism

200 million years ago in the late Paleozoic Late Carboniferous to Late Permian, a worldwide crustal movement occurred, known as Late Variscan, in the southern margin of the Tarim continent, ancient land mass of the continental margin of land and activities with the middle block in the strong faulting and magmatic activity along the fault zone are penetrated in the acidic intrusive rocks dolomite marble. Residues in the intrusion at the top of dolomite marble xenoliths or tongue body and magmatic intrusion and hydrothermal contact metasomatism, the formation of diopside petrochemical, forsterite, and tremolite alteration of, as the material conditions of Chengyu one.

IV Chengyu stage

Late Variscan intrusions in the shallow derived acid dykes intruded into dolomite marble altered with time, repeated exposure to metasomatism, in the appropriate geological conditions (300-350 degrees Celsius, 2.5 kbar the following and some twisting stress), the final formation of Hotan jade.

above can be summarized in four stages as follows:

A, the late Proterozoic epicontinental sea sediments / sedimentary dolomite (as a source of jade material)

B, the late Proterozoic Tarim sports, regional metamorphism / dolomite to dolomite marble metamorphic rock (as jade material structural modification)

C, Late Variscan intrusive activities of acid, contact metasomatism / alteration zone of the formation of dolomite marble (the material basis as Jade)

D, Late Variscan intrusions in the acidic dikes derived metasomatism Contact / Hotan Jade Jade Jade difference between the formation of jade and jade some confusion in the use of the terms, early, and now some people more than the jade and jade mix, the same use. so far in the technology sector and the general public and the profession is still not distinguish between rocks. However, many academics tend to separate the jade and jade, jade, jadeite and nephrite refers specifically; and jade were used collectively, including the appearance of jade jade and those formed by the mineral aggregates your beautiful stone.

the difference between precious stones and jade

always someone on the difference between emerald and jade are confused because they are transparent and exudes a charming green sheen. In fact, and nephrite jade, and belong to two completely different areas: emeralds are precious stones, and jade is jade. So, the difference between precious stones and jade is it? Generally speaking, is derived from natural single crystal gem mineral, which means that a gem is usually taken from a single crystal, crystal with our naked eye can see (so called was crystal), precious stones are usually transparent, light after cutting the stones into the house, after a series of reflection and refraction, we can see the flash of gems such as rubies, sapphires, emeralds, etc.; there are a few gems are natural single-mineral aggregates, such as opal, lapis lazuli, but also There are some organic matter, such as amber, pearls, coral, ivory, precious stones are also included in the broad sense within, they are called bio-jewels. The jade is another concept, it is by numerous small naked eye can not see our crystals only in the high-power electron microscope we can see its structure, so people called aphanitic jade minerals, generalized to that the aggregation of these small crystals can be called jade. Usually when people talk about the main reference is the jade and nephrite (a typical white color) and emerald (green for the typical color), both internationally recognized as jade is more valuable jade. Stones are usually transparent, due to a very smooth surface, so the ability to reflect light gem surfaces relatively strong, and light can enter the house through the reflection and refraction of gems and then leave the stones to reach our eyes, we see a high degree of cut net gem almost always shining. The jade because it is composed of numerous tiny crystals, there are always gaps between the crystals, so no matter how polished the master processing, and can not achieve the level of smooth surface stones, the light path in the jade as the sun formed on the surface sprinkle with the waves on the lake, this effect is also known as diffuse reflection. If you are interested in comparing the surface gloss, you can carefully look at their own ground-glass windows and shower room difference, whether it is more smooth and shiny, the stronger it? So we often see the surface of jade or oily texture is moist. Because light can penetrate little gem inside, so we often feel translucent jade is, of course, are some exceptions, the top of the emerald can be almost transparent.

Jade - the precious jade reasons

First of all, Jade looks like good-looking, rich colors. Ancient books, Jade color grass green, light green, dark green, gray, white, colors deep and soft, smooth and warm to form a unique color. Chinese people like a translucent white, yellow and even white

Secondly, the ancient superstition that evil Jade has the role of anti-demon. Made with jade cups, bowls, plates and other utensils and ritual jade bracelets, Hosta, rings, cigarette holder and other accessories.

Third, jade toughness, to withstand the hammer blows, this feature can not be compared with diamond. Jade color and the use of the advantages of various shapes can be carved animals, plants, pavilions, pagodas and other fine crafts and decorations.

1935 years, a major earthquake struck Southern California, Santa Barbara, a small collection of Chinese art crafts store fell into the ground. But the good news is that the owner, the most valuable jade products although the top level on the shelf, but one has not been damaged. Obviously, jade is very tough.

Jade Qing Dynasty Empress Dowager Cixi greed

jade life. It is said that those who have a tribute dedicated a large diamond tiara, she did not accept, but welcome given to her small but beautiful She has a valuable ring, shaped like a small cucumber, high-quality jade is carved. Jade bracelet on her wrist, several fingers on the wearing of fine jade jade ring and three-inch-long nail sets, eating and drinking with a carved jade plate, jade chopsticks and jade bowl. After her death a large number of jade sacrificial victims treasures.

is the world's largest jade Yun California 1971 Terre mined near the sea, weighs 5 tons, was named as the up to 28 tons of soft jade. discovered in 1978 in a piece of Burmese jade larger, weighing 90 tons. But as early as 1960, Xiuyan County, Liaoning Province in China out of a large jade mining, the volume of 106.8m3, re- of 267.76 tons, compared with three jade abroad more than 204.05 tons total weight, fine texture, transparency, and is the world's true because they are transparent and exudes a charming green sheen. In fact,UGG bailey button, and nephrite jade, and belong to two completely different areas: emerald are precious stones, jade and emerald are. So, the difference between precious stones and jade what is it? Generally speaking, is derived from natural single crystal gem mineral, which means that a gem is usually taken from a single crystal, crystal with our naked eye can see (so called was crystal), precious stones are usually transparent, light after cutting the stones into the house, after a series of reflection and refraction, we can see the flash of gems such as rubies, sapphires, emeralds, etc.; there are a few gems are natural single-mineral aggregates, such as opal, lapis lazuli, but also There are some organic matter, such as amber, pearls, coral, ivory, precious stones are also included in the broad sense within, they are called bio-jewels. The jade is another concept, it is by numerous small naked eye can not see that we crystals, only in the high-power electron microscope we can see its structure, so people called aphanitic jade minerals, a broad sense, a collection of tiny crystals can be called jade. usually referred to people talk about mainly refers to jade and nephrite (the typical white color) and emerald (green for the typical color), which is currently recognized as two jade jade more valuable. gemstone is usually transparent, due to a very smooth surface, so that the surface of stones relatively strong ability to reflect light, and light can enter the house through the reflection and refraction of gems and then leave the stones to reach our eyes, we see a high degree of cut gems net almost always shining. and jade because it is numerous small crystals,UGG shoes, there are always gaps between the crystals, so no matter how polished the master processing, and can not achieve the level of smooth surface stones, the light path formed on the surface in the jade as the sun shines on the lake with waves , and this effect is also known as diffuse reflection. If you are interested in comparing the surface gloss, you can carefully look at their own ground-glass windows and shower room difference, whether it is more smooth and shiny, the stronger it? jade so we usually see the surface is moist or oily texture. because of the light can penetrate little gem inside, so we often feel translucent jade is, of course, are some exceptions, the top of the emerald can be almost transparent.

cultural development of Chinese jade Chinese jade culture has a three-stage the initiation of a thousand years long history of development. It has infinite vitality, the 2008 Beijing Olympic Games emblem is an ancient cultural tradition and contemporary Olympic jade human values the outstanding combination of work, it is old and young Chinese jade culture and a powerful witness. divided into age

jade identification, function, jade, shaped ornaments, engraved, and the name, value, price of certain information, which is the first time (s) identified. Time (s) identified can be divided into macro age (years) and the microscopic identification period (s) identified two broad categories. Identification of the times than the era of the macro to even at the smallest amount of standard time. To These three stages are the largest jade identification of macro-times, the longest cut-off level, this is identified we must first grasp the basic concept of the era. God Yu-phase years ago, Wu Yu-stage 10000-4000. Jade prehistoric cultural development and prosperity is driven by God. God is created by the Witch, and she (he) rely on God's power to rule society. Witch jade reflected image, as seen in Hongshan Yumian, Dasi, Lingjiatan,bailey UGG boots, Liangzhu, Shijiahe other prehistoric cultures. In Northeast China, southeast, northwest of the Yangtze River and the five other places rich jade resources to promote the development of a huge prehistoric society has formed three jade culture plate and five sub-branch of jade culture plates, for the laying of the cornerstone of Chinese civilization. As from the Xia Zhiqing Wang Yu-stage phase (dynasties - the Qing Dynasty). Wang holds the production, use jade power. Three generations to Qinhan Cheng Wang Yu as the emperor. The main function of jade ritual (Thallium machine as bronze or iron. Jade dynasty era has its own style, very clear, this is the objective and clear evidence of the Style Identification. Spring and Autumn Period Confucius and Confucianism has made an important contribution to the upcoming Yu freed from God, to the China Jade Culture Jade stage between the Wang stage in among the people of jade culture has gradually formed and developed, from the Song to Qing China's jade culture in China Jade stage (Song - Qing Dynasty). In addition to special court for the king of jade, the jade, owing to business development and commercial production, industry and commerce, the court prohibited the expense of well-off family home, purchase of jade from the shop for happy, wear, Wen rooms, banquets, appreciation, collection, etc. material and cultural lives. China Jade Jade is a commodity, there is no special ritual jade class property, and Wang is different from the characteristics of the people of jade is closer to civil life, with a lively fresh style.
