In China Jade explicitly called jadeite (chalchiguite), probably began in the Song Dynasty. After the second half of the 19th century, the French mineralogist De Mul China's "Jade" and is divided into nephrite represented Nephrites nephrite and jadeite (see Geological Information Institute: "Jade rushing" foreign geological science and technology ", the first in 1981 2) categories.
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 mat, fitness ball, massage, walking stick, jade comb, the human body has the beauty, calm and soothe the nerves of the efficacy of long-term use, will make you filled with energy and longevity.
Jadeite chalchiguite commonly known as "Jade", is a rising star in China's traditional jade, jade is in the top grade in all modern.

Emerald chalchiguite common colors are white, gray, pink, light brown, green, green, yellow, purple, etc., most opaque, individual translucent, shiny glass. Divided by color and texture, there are gems green, brilliant green, green, yellow sun, Yang Qiao green, green glass, parrot green, spinach green, shallow green, light green sun, green frog, green melons, green plum, blue and green , gray-green, glossy dark green, and violet and lotus root starch to over 20 varieties.
Jade hardness 7, specific gravity 3.33. Mineral Refractive index: Ng = 1.667, Np = 1.654 ; 0.012 birefringence.
While the Han Zhang Heng "Xijing fu", Ban Gu's "West Ode" and the "New Order Wing" Six Xu Ling jade mentioned are likely to refer to the nephrite jade, jadeite instead. Because of jadeite in the Tang Dynasty
jade chalchiguite whether it is "Mountain material" (original ore) or "seed material" (secondary minerals), mainly dense block of jadeite mineral composition. Observed under a microscope, they were closely Jade jadeite mineral composition together to form a fibrous structure jade. This tight fibrous structure, the emerald has a delicate and tough characteristics.
Jadeite chalchiguite silicate is a mineral composed of steel and aluminum, Zhe pure colorless or white. Its chemical composition of the block is: silica accounted for 58.28%, representing 13.94% of sodium oxide, calcium oxide accounts for 1.62%, magnesium accounted O.91%, ferric oxide accounts for O.64%, and a slight amount of chromium, and nickel. Among them, chromium is a major factor in the emerald has emerald green. Typically Emerald chromia O.2 ~ O.5%, more than 2 individual to 3.75%.
Generation has not test, so Annotation "Selected Works," Analysis of the Functions to the "Han" are a bad idea and it. British historian Joseph Needham in the third volume of "History of Chinese Science and Technology," said: Before the 18th century, Chinese people do not know this kind of thing jadeite. Later, jadeite from Burma origin only via Yunnan into China. Not long ago, Soviet geologists base also Fulin Ke also pointed out that the degree of risk of Myanmar, Myanmar to take, take and Nan Nai Pan risk of secondary emerald mine was discovered in 1871, has been mined for over a hundred years, has not yet taken air. Myanmar Wulongjiang native Emerald Valley as early as the 13th century (the late Song to the early Yuan) has been mining (see "Foreign Geological Science and Technology"). In China, from the palace treasures and relics not been found before the Ming Dynasty jade. Therefore, the Chinese people when called jadeite jade chalchiguite is, when Myanmar jade into China, has been a history not figure out the mystery. We look forward to the archaeologists have to have a new discovery, to resolve this outstanding historical issues.
Jade's health mechanism has been confirmed by modern science. According to chemical analysis, jade contains a variety of microelements such as zinc, magnesium, iron, copper, selenium, chromium, manganese, cobalt, wearing jade can trace elements absorbed by human skin, activate cells and tissues, enhance the body immune function. Therefore, the Chinese say, "Some medicine can not cure the disease, but often wear jade cure disease", the reason this is it. If wearing jade bracelets long-term healthy massage, passive addition to blurred vision not only of the disease, but also build strength, raise the spirit.
