To build an internationally renowned synthetic diamond cutting and polishing center, China should focus on the following aspects:

1. Seize the opportunity of industrial transfer and vigorously develop new quality productivity. With the development and maturity of modern automated synthetic diamond cutting techniques, it will inevitably bring about technological innovation and industrial transfer in this field. As the world's largest producer of synthetic diamonds, China should seize this historical opportunity and use highly innovative automated cutting methods to create new quality productivity and empower the entire synthetic diamond industry.

2. Drive the development of industrial clusters through technology introduction. Currently, China's synthetic diamond cutting sector has not yet formed a complete industrial cluster. There is only a scattered distribution of small and medium-sized factories in Shanghai, Shandong, Liaoning, Guangdong, Henan, and other places, lacking comprehensive supporting facilities. To change the current situation of relying on Indian companies for cutting and polishing, China should use technology introduction to drive industrial clustering, treating it as an opportunity for development, thereby promoting the perfection of the local supply chain and the establishment of an internationally renowned cutting center.

3. Utilize automated processes to lower the technical threshold and promote the miniaturization of cutting factories. Traditional diamond cutting highly relies on the experience of technical workers and master craftsmen, resulting in an extremely high industry threshold. However, modern automated cutting techniques greatly reduce manual intervention by introducing precision instrument scanning, three-dimensional modeling design, laser cutting, and automatic grinding machines with rough grinding wheels. This technological innovation significantly lowers the technical threshold for cutting, making it easier for the cutting industry to move towards industrialization and small cutting mills.

4. Fully leverage the huge cost advantage of automated cutting. Modern automated synthetic diamond cutting techniques can bring extremely high production efficiency and a significant reduction in costs. According to research and calculations, the manual cutting fee in India is about 300 to 400 RMB/carat, and the domestic manual cutting fee is even higher at 400 to 600 RMB/carat. However, if the automated synthetic diamond cutting factories are moved to inland China, the automated cutting fee can be drastically reduced to 60 RMB/carat. Fully utilizing this huge cost advantage will greatly enhance China's core competitiveness in the global diamond processing market.
