China is a huge potential market of diamond consumption. According to an investigation made by the De Beers Central Marketing Organization in 1995, by 2000 the consumption population of diamond jewelry in China will increase by 50% and the purchasing amount will grow by 47%. It is expected that China will rank among the largest consumers of diamond jewelry. According to reports, in 1996 the domestic marketing amount reached 60 billion RMB yuan and the export volume reached US $ 1.2 billion. In jewelry, 58% of people like diamonds. It is estimated that the consumption of diamonds in the whole country is about 14.64 billion RMB yuan (c. US $ 1.76 billion) per year. It is evident that the production of gem diamonds in China"s current annual production of 120,000 carats of diamonds falls far short of the domestic demands of China. Owing to the serious shortage of natural diamonds, industrial diamonds now are mainly synthetic diamonds, which account for over 99% of the consumption, while natural diamonds for industrial uses make up less than 1%. The annual domestic consumption of synthetic diamonds in China does not exceed 100 million carats. They are mainly consumed in building stone...more

Diamond is a crystalline form of carbon under high temperatures and pressures and the hardest mineral known in nature. It is a rare, precious nonmetallic mineral and plays an important role in the national economy. According to their uses, diamonds can fall into two categories: those that are of high quality and coarse-grained and can be used as decorations are called gem diamonds, and those that are poor in quality and fine-grained and used for industrial purposes are called industrial diamonds. Gem diamonds are remarkably brilliant, glittering and transparent, reputed as the "king of gems". They are highly valued, known as the world"s first goods. The levels of their occupancy and consumption are usually considered as the indication for judging the richness of a person and the economic prosperity of a country. Diamonds that are not up to the gem quality are widely used for industrial purposes owing to their great hardness, such as in electromechanical equipment, optical instruments, building, transport, metallurgy, geological exploration and national defense, as well as in high and new technological fields. According to the trace elements contained, diamonds may be classified...more
