This article explores the shifting fortunes of China’s synthetic gem industry through the lens of veteran worker Cen Jiantu. It highlights the sector’s initial promise, its subsequent challenges, and the broader economic transitions affecting traditional manufacturing hubs.

Like many of his fellow workers, Cen Jiantu chose one of the city’s highest-paying sectors — the synthetic gems industry — when he entered the job market two decades ago.
The reputation of Wuzhou, a city in South China’s Guangxi Zhuang autonomous region, as the global hub of synthetic gems remains as bright as ever.
Synthetic gems are lab-made stones that look and feel like their natural counterparts, such as diamonds, rubies and emeralds, but at a fraction of their price. The industry rolled out in Wuzhou four decades ago, leveraging the city’s comprehensive logistics network, ample labor supply and other advantages.
Moissanite is a naturally occurring and laboratory-grown mineral used as a diamond alternative.
Now, thanks to technological advances and improved materials, Wuzhou is poised to reach a new level of success, according to industry insiders.

Wuzhou is home to 70 percent of global synthetic gemstone production. The number of stones processed, distributed and traded in the city last year exceeded 100 billion, with the comprehensive output value reaching about 10.7 billion yuan, according to the latest industry figures.
With young consumers forming a major segment of the market, there are “unprecedented new opportunities for the development of synthetic gemstones offering competitive prices and high quality”, Jiang said.
Policy support for small and medium-sized enterprises, in exploring the international market, pursuing product certification, obtaining overseas patents and trademark registration, establishing research and development, and training talent, will help the industry grow further, Jiang said.
The sector has also seen significant improvements in green, sustainable production with improved technology, reducing any environmental impact, she said.

Wuzhou Mayor Zhong Changzi said the city is rolling out a gemstone industrial park to improve support for related services, help guide enterprise development, enhance technological innovation, product innovation capabilities and quality, and create leading local brands.
Rao Guiqiang, who is in charge of Xuping Jewelry’s Wuzhou operations, said the city is well-placed at the center of the industry.
Zhong, the Wuzhou mayor, said that efforts must be made to take advantage of “major strategic opportunities” offered by countries participating in the Regional Comprehensive Economic Partnership agreement, the world’s largest free trade pact, and the Belt and Road Initiative, and to “vigorously develop cross-border e-commerce and extend overseas sales channels”.
