China News Service, Zhengzhou, November 12 (Reporter Han Zhangyun) Recently, the "Action Plan for the High-Quality Development of the Cultivated Diamond Industry in Zhengzhou (2026-2028)" was issued. As the first city in the country to single out the "cultured diamond" industry to encourage its development, Zhengzhou, the capital of Henan Province, is striving to build a "cultured diamond capital" and strive to achieve a total industry scale of 20 billion yuan in 2028.

On November 12, the Zhengzhou Municipal Government Information Office held a press conference on the "Zhengzhou City's High-Quality Development Action Plan for the Cultured Diamond Industry (2026-2028)" to inform on the development status and planning of the city's cultured diamond industry.

Zhengzhou has a solid foundation for developing the cultivated diamond industry. Zhengzhou is the birthplace of China's superhard materials industry. In 1963, China's first artificial diamond was successfully developed in Zhengzhou, laying the foundation for China's cultivated diamond industry.

"Zhengzhou, as the core production area of ​​HPHT (high temperature and high pressure method) cultivated diamonds and the main distribution center in the country, has outstanding industrial foundation and technological advantages." Gao Donghui, deputy director of the Zhengzhou Municipal Bureau of Industry and Information Technology, said that there are currently more than 100 enterprises in the cultivated diamond industry chain in Zhengzhou, with an annual output of about 6 million carats of rough cultivated diamonds. Huajing's diamond production capacity ranks among the top in the country; Sifangda specializes in large single crystal white diamonds and pink diamond roughs of 3 to 6 carats, which shows Zhengzhou's leading position in the field of mass production of large-size, high-grade cultivated diamonds; Muziyuan, Taiwan Diamond and other companies have been deeply involved in diamond cutting and grinding for many years and have deep technical accumulation.

Zhengzhou has designed a clear path for industrial development on how to build a "city of cultivated diamonds".

"It is estimated that the scale of Zhengzhou's cultured diamond industry will reach 20 billion yuan by 2028, mainly because the cultured diamond industry will show explosive growth in the next few years." Liu Yatao, deputy secretary-general of the Zhengzhou Municipal Government, said that Zhengzhou, as the processing and distribution center and export hub of cultured diamonds in Henan Province and the core area of ​​the Zhengnan Shangxu Superhard Materials National Advanced Manufacturing Cluster, is facing unprecedented development opportunities and has the conditions and ability to build cultured diamonds into a tens of billions of emerging industries.

Currently, Zhengzhou is transforming its lab-grown diamond production capacity advantages into trade and channel advantages by exploring foreign consumer markets, strengthening its e-commerce live broadcast platform, building a lab-grown diamond trade distribution hub, and building a bonded trading center.

Wang Yun, deputy director of the Zhengzhou Municipal Bureau of Commerce, introduced that the development model of "cultured diamond industry belt + live broadcast e-commerce" is supported, and the live broadcast e-commerce is promoted from the "sales window" to the integrated node of "product selection-testing-contract fulfillment". Relying on the existing live broadcast base and cultivated diamond promotion and operation center, the live broadcast agencies are guided to be deeply bound to cutting, setting, testing and other links. "Let consumers see not only the price in the live broadcast room, but also traceable testing information and reliable delivery guarantee."

China is the world’s largest supplier of rough lab-grown diamonds. Currently, domestic lab-grown diamond production capacity continues to gather in Henan. From January to September this year, Henan's lab-grown diamond exports reached 15.8 million carats, a year-on-year increase of 116%. Among them, Zhengzhou's lab-grown diamond export value ranks first in the country.

Wang Yun introduced that Zhengzhou will strengthen cooperation with the Shanghai Diamond Exchange and other units, promote the establishment of a Henan service center in Zhengzhou, and strive to achieve local processing of customs declaration procedures for the import and export of cultivated diamonds; accelerate the construction of a cultivated diamond bonded trading center and a diamond duty-free shop at Xinzheng Airport, and introduce industry chain enterprises into Area B of the Zhengzhou Economic Development Comprehensive Bonded Zone to create an international trade base for cultivated diamonds that radiates domestically and reaches the world.
