Zhecheng County in China has become the nation’s top producer of lab-grown diamonds, transforming from a poor farming region into a high-tech industrial hub.
Zhecheng County in Henan Province, once a poverty-stricken farming area, has become China’s "Diamond Capital," producing nearly half the nation’s lab-grown diamonds.
Using high-pressure, high-temperature technology, local factories create diamonds in days, offering high-quality stones at a fraction of natural diamond prices.
The transformation has spurred economic growth, with 65 retail stores, over 600,000 annual tourists, and a thriving industrial cluster of 200+ companies, including specialized "little giant" enterprises.
Beyond jewelry, Zhecheng’s superhard materials support oil drilling, aerospace, automotive, and semiconductor industries.
The county is expanding into advanced applications like semiconductor cooling and optical components, backed by government incentives and growing R&D investment.
