With the maturity of synthetic diamond technology and rapid development of Chinese economy, we make great progress on manufacturing technology of diamond tools. Chinese enterprises have obvious advantages on cost, performance and value of products because of low labor cost and fast development of technology. In order to meet the needs, many enterprises start to produce diamond tools. China has become the key country of diamond production, application and export in the world. The annual output is more than 10 billions.

With the continuous improvement of quality, synthetic diamond is expected to further extend in emerging field. Its excellent performance is widely used in high-new technology field, for example, aircraft instrumentation, radar waveguide, optical devices, etc. The developed countries have focused their attention on developing superhard materials and products. The research and application level represents science and technology development level of one country to a certain extent.

The demand of synthetic diamond increases fast in the future. According to the statistics of industry association, the production and sales of diamond has increased from 1.6 to 5.4 billion carats in 2001-2009, with an average annual growth rate of 16.4%. The export amount has increased from 0.153 to 1.35 billion carats in 2001-2008, with an average annual growth rate of 37%. The domestic demand will be 7 billion carats in 2012.
