In recent years, Zhecheng County in Henan Province has rapidly emerged as a major global hub for lab-grown diamond production, thanks to its advanced technology and comprehensive industrial chain. According to the latest data, the county now produces 12 million carats of lab-grown diamonds annually—accounting for over 70% of China’s total output and ranking first nationwide. Building on its strong foundation in superhard materials, Zhecheng has continuously enhanced both technological innovation and production capacity, employing methods such as High-Pressure High-Temperature (HPHT) and Chemical Vapor Deposition (CVD). The region is now home to hundreds of related enterprises, forming a complete industrial chain that spans raw materials, equipment manufacturing, R&D, finished product processing, and sales. Moreover, Zhecheng is actively promoting its ‘Diamond Capital of China’ brand, expanding applications of lab-grown diamonds in jewelry, industrial sectors, and international markets. As global consumer demand grows for sustainable and eco-friendly gemstones, Zhecheng’s lab-grown diamond industry stands at the threshold of unprecedented opportunities and is poised to play an increasingly significant role in the global diamond market.
