目前世界上有26个国家发现具有工业价值的金刚石矿床.金刚石储量居世界前列的有澳大利亚、扎伊尔、博茨瓦纳、南非和苏联.金刚石在自然界非常稀缺,找到具有经济价值的矿床极为困难.金刚石不仅是名贵的宝石,随着现代工业和科学技术的发展,金刚石的使用范围正在不断扩大,在工业上的用量越来越多,Ⅱ型金刚石是国防工业和尖端科学不可缺少的重要原料.近几年,世界金刚石的年总消耗量约1.5亿克拉,其中人造金刚石占2/3.
At present, there are 26 countries in the world that have found industrially valuable diamond deposits. Diamond reserves are among the highest in the world in Australia, Zaire, Botswana, South Africa, and the Soviet Union. Diamonds are scarce in nature and finding economically valuable deposits is extremely difficult. Diamond Not only are precious gems, with the development of modern industry and science and technology, the use of diamonds is continuously expanding, and the amount of industrial use is increasing. Type II diamond is an indispensable important raw material for defense industry and cutting-edge science. In a few years, the total annual consumption of diamonds in the world is about 150 million carats, of which artificial diamond accounts for 2/3.
