A brief history of the development of the diamond

HumansDIAMONDUnderstanding and development has a long history. Early in the third century BC in ancient India discovered the diamond. Since the Christian era until now, it has been the country with the diamond aristocratic palace dignitaries of wealth, power, status symbol.

World diamond mineral resources are not abundant, in 1996 the world's proven reserve base of only 1.9 billion tons of diamond, gem and can not meet the needs of industrial consumption.

Since the 1960s, the rise of synthetic diamond technology, to improving the 1990s, synthetic diamond for industrial use has almost completely replaced natural diamond, more than 90% of its accounts for the world's industrial diamond consumption (in China has reached 99% ).

The main diamond producing countries as Australia, Russia, South Africa, Botswana and Zaire. World diamond distribution is mainly controlled by the DeBeers Central Selling Organization.

China found the diamond about 200--300 years ago,Qing MingThe occasion (about 17th century), scouring the river sand in Hunan farmers visited the diamond. Diamond geological exploration work began in the 1950s. So far, the Chinese found weighing more than 90 ct diamond has six well-known, such as weighing about 158 ​​ct of "Chang Lin Diamond" and so on. China Diamond relatively poor in mineral resources, geological work for nearly 50 years, only in Liaoning, Shandong, Hunan and Jiangsu four provinces proved reserves. By the end of 1996, China retains diamond reserves of 0,897,800 ct, in the world, it does not occupy an important position. In terms of quality, Liaoning Province, China produced good quality diamond, gem-quality diamond production accounts for about 70% of total production. Since the 1990s, China with an annual output of about 10 to 150,000 diamond ct, can not meet the needs of their consumption. Diamond industrial countries needed more than 99% dependent on the domestic synthetic diamond, synthetic diamond production in China in 1997 reached 440 million ct, the share of natural industrial diamond consumption ratio is very limited.

Diamond ore magmatic rocks and alluvial categories. Known diamond-bearing kimberlite rock there, lamproites and eclogite three kinds, including kimberlite type and lamproite type of industrial importance.

According to the British "Daily Mirror" September 17, 2012 reported that the Russian Kremlin announced that a crater in Siberia discovered asteroid collision formed diamond-rich resources, the sustainable development of the large storage capacity of up to 3,000 years . This crater is named Poppy cover pit, about 100 kilometers in diameter, which contains up to several trillion diamond carats of diamonds over existing reserves worldwide. According to reports, the reason for so many years Poppi pit lid has not been developed, becauseSoviet UnionTimes people put more effort spent in the build artificial gemstones.Diamond expert root Nadi · Niji Ting pointed out that "large reserves of diamonds shocked people, what kind of impact on their development will give the diamond market is not yet clear." Root Nadi added, and manufacturing Jewellery compared the value of these diamonds will be more reflected in industrial applications.
