Jade has a history in China of at least four thousand years. Unknown to some, it is found contained within the development of religion and civilization, having moved from the use of decoration on to the others such as the rites of worship and burial. Although other materials like gold, silver and bronze were also used, none of these have ever exceeded the spiritual position that jade has acquired in people’s minds – it is associated with merit, morality, grace and dignity. In the funeral objects of the people of the Western Han Dynasty (206 BC – 24 AD), for example, we can see only high officials were buried with jade articles.
Jade has influenced all walks of life. In ancient times, people expressed abstract notions with concrete patterns of Chinese character, which were influenced by Taoism and Buddhism. Jade craftworks were among the most precious and luxurious ones; people wore and decorated rooms to indicate loyalty, elegance, beauty, and eternity. The most popular patterns were: peach (longevity), mandarin duck (love), deer (high official ranks), bat (blessing), fish (affluence), double phoenixes (thriving), bottle (safety), lotus (holiness), bamboo (lofty conduct), and fan (benevolence), etc.
Types of Jade
As early as the 16th century, it was believed to be a precious and hard jade with healing qualities for the human stomach and kidneys. Since it was brought into China during the early Qing Dynasty (1644 – 1911), it had been doted on greatly. It contains an iron component which appears red, chromium that appears green, and many other colored types. Known as the ‘king of jade’, it is usually a more expensive type.
Nephrite’s robustness is due to the fact it contains tremolite. It also can be divided into several sub-classifications according to color: white, grey, green, topaz, and black jade.
In China, the most reputable jade producing area is Hetian in Xinjiang Province. Hetian jade is so hard that it can scratch glass. It has often been found in very huge pieces.
Serpentine jade, or Xiu yu in Chinese, is mainly from Xiuyan County in Liaoning Province. Made of many different ingredients, it takes on various appearances: white, yellow, light yellow, pink, green, dark green, light green and so on. This type is usually coloured in various shades of green. Usually serpentine jade is semi-transparent or even opaque like wax.
Lantian jade is produced in Lantian County, north of Xian in Shaanxi Province. It was also among the most charming ancient jades, for its rigidity made it easier to be carved into decorations and jewelry by our ancestors. The hue is uneven in colors of yellow or light green.
Nanyang County in Henan Province is famous for its abundant Nanyang jade. The ore district is located on an isolated 200 meter high hill, called Dushan Hill (thus its other name of ‘Dushan jade’). It is distinctive for its whimsicality. Among the Nanyang jade artworks, you will find rare purple, blue and red ones.
How to Appreciate and Maintain Jade
Experts believe that, although more expensive, diamonds and gold cannot be compared with jade – it is animated with a soul. They often buy to collect their favorite jade artworks, while people with little knowledge may buy coarse works.
To obtain a real jade article, you should take pains to learn and appreciate it. The criteria lie in the brightness of color and luster, compactness of inner structure, and the delicacy of the craftwork. For example, nephrite creates an oily luster and jadeite creates a vitreous luster. Tiny cracks can lower its value; on real one, air bubbles cannot be seen; the more lenitive the higher quality of jade, and so on.
Having purchased a jade article is just half the process of collecting. It is like a child that needs constant care. Enthusiasts need to work more to maintain this artwork, or blemishes may appear.
First, avoid bumping into hard surfaces as it is delicate. Although sometimes a crack cannot be seen by the naked eye, the interior structure may have been damaged. As time goes on, it will appear and reduce the value of the piece.
Second, protect it from dust or greasy dirt. If tainted, they must be scrubbed with a soft brush and light suds and washed with clean water.
Third, when left unused it is best to store it in a case or box to protect it from being bumped.
Fourth, it should be kept away from perfume, perspiration or chemicals. Its brightness risks corrosion, especially emerald and other high quality jade, so it is better to clean it with a soft cloth after wearing it.
Fifth, do not expose it to sunlight for a long time, or it may expand and the quality will change slightly.
Finally, jade has certain water content so keep it in an area of humidity to protect it from over-drying.
