What National Gemstone Testing Center does

National Gemstone Testing Center (NGTC / 珠宝国检集团) is a state-owned enterprise operating under the Ministry of Natural Resources of China, founded in 1993 and headquartered in Beijing. It functions as China's official national authority for gemstone, jewelry, diamond, and precious metal testing and certification, operating a network of 17+ laboratory locations across major Chinese cities including Beijing, Shanghai, Guangzhou, Shenzhen, Kunming, Hangzhou, Suzhou, Hong Kong, and origin hubs such as Hetian, Zhushan (turquoise), and Longling (jade). Beyond inspection, NGTC certifies 60,000+ jewelry industry professionals across 54+ skill appraisal sites, hosts the SAC/TC298 national gemstone standardization secretariat and the AGA Asia-Pacific standardization alliance, and is CNAS-accredited (PT0071) as a proficiency testing provider.

Its product portfolio spans four pillars: (1) Testing Services — gem identification, diamond grading, and precious metal elemental analysis using microscopes, infrared spectrometers, and other industry-standard instruments; (2) Training Services — vocational education and professional certification delivered through training centers in Beijing, Shanghai, Guangzhou, and Shenzhen, plus national skills appraisal under Ministry of Human Resources filing S0013; (3) Digital Services — the 玉源码 (Yuyu Code) intelligent anti-counterfeiting traceability system, the Gold Product Digital Passport, and the NGTC mobile app supporting NFC, QR code, and ID-based certificate verification; and (4) Instrument R&D and Standardization — development of specialized testing equipment plus operation of national and international standards bodies.

NGTC's business model combines professional services revenue (testing fees per item, training tuition), subscription/recurring revenue (digital traceability platforms, certificate verification), and hardware sales (instruments). Pricing is not publicly disclosed and varies by service complexity. Go-to-market is a hybrid of direct enterprise field sales through 15+ physical labs, on-site exhibition testing at major jewelry shows, multi-channel consumer education via WeChat/Weibo/Douyin/Toutiao/Kuaishou (4.645M viewers at one 3.15 livestream event), and strategic partnerships with municipal governments, e-commerce platforms (JD.com, Taotao Group), major retail brands (Zhou Dafu, Lao Feng Xiang, China Gold, Edison Pearl, Mengjinyuan), and Xinhua News Agency for international communication.
