Introduction Of Diamond Trade
Although China is considered to be a relative newcomer,it is becoming an effective manufacturing center. Inexpensive labor being its main advantage, a few foreign sightholders "outsource" there; and a number of Hong Kong based companies (as well as some from Israel, Belgium and India), have cutting and polishing facilities there. Labor costs in Shanghai factories, and a few in Guangdong, are said to be comparable with Bangkok; whereas, inland, costs are closer to the diamond cutting costs in India.
China imports approximately USD$500 million of rough diamonds annually, and specializes in the sawn and sawable categories of rough (that don't demand high technology). Some factories are already cutting fancy shapes, and others, in southern China, have been cutting larger goods (up to 2.00 carats). There are 3 rough diamond mining areas in China: the Wafangdian Mine, in Liaoning province in northeastern China; an area of alluvial diggings in Hunan province in the central part of the country; and, the Mengyin Mine in Shandong province; the rough, most of which is exported, includes assortments from $30 to $125 per carat.

Diamond Mining in China
Diamonds were found in China about 200 to 300 years ago. Between the Ming and Qing dynasties (in c. the 17th century), farmers in Hunan Province panned river sands and reco-vered diamonds from the placers. Geological exploration for diamonds began in the 1950s. Up to now six famous diamonds, each with a weight greater than 90 carats, have been found in China; for example, "the Changlin diamond" weighs about 158 carats.
Little is known about the quantity and quality of diamonds produced in China, although there seems to be great potential. Detail..
Diamond Resources in China
Diamond resources are not abundant in the world. In 1966 the world's explored diamond reserve base was 1.9 billion carats, falling far short of the demands of gem and industrial consumption. In the 1960s synthetic diamond technology arose, and by the 1990s the technology has been perfected. The synthetic diamond has almost all replaced the natural industrial diamond, and its consumption has taken up over 90% of the world's industrial diamond consumption. Detail..
Introduction of Chinese Jewelry

According to the statistics, the current annual sales of Platinum has amounted to 1.4 to 1.5 million ounces, the annual consumption of diamonds has exceeded $1.1 billion, the annual demand for gold jewelry has reached approximately 200 tons and the growth rate of jewelry consumption maintained 15 percent in recent years in China.
Currently, the annual sales for jade and pearl jewelry, diamond jewelry, and gold jewelry are RMB 40 billion, RMB 30 billion and RMB 30 billion respectively in China, making China an attractive market to the whole world...
