Visit and discuss cooperation
On Tuesday, September 16, 2025, a delegation from the Guangdong International Diamond Chamber of Commerce, led by Executive President Yin Xiuhua and accompanied by Laboratory Director Hu Jianhua, visited the GIL International Gemological Laboratory to experience the lab's testing procedures and diamond grading standards. The two sides then engaged in efficient and detailed discussions on the details of their collaboration and agreed to sign a strategic cooperation agreement on September 19, 2025.
Working together to create a blueprint for the future
On Friday, September 19, 2025, the Guangdong International Diamond Chamber of Commerce and GIL International Gemological Laboratory, a leading international gemological testing organization, officially signed a strategic cooperation agreement. This collaboration not only demonstrates the leading position of both parties in the industry but will also propel the cultured diamond industry towards a new stage of standardized development.
In recent years, diamond cultivation technology has achieved breakthroughs in crystal growth, color control, and clarity enhancement. The two mainstream techniques, HPHT (High Pressure, High Temperature) and CVD (Chemical Vapor Deposition), are now capable of producing high-quality diamonds with D color and IF clarity, and have even achieved remarkable results in the cultivation of large diamonds (over 5 carats).
During the hours-long discussion, the two sides engaged in a multi-faceted discussion on the future development of cultured diamonds. The cultured diamond market is rapidly growing at an annual rate of over 20%. This explosive growth is driven not only by technological advancements but also by the preference of young consumers for sustainable jewelry.
Leveraging cutting-edge spectral analysis technology and a unique crystal growth pattern detection system, GIL International Gemological Laboratory accurately identifies the production methods and processing techniques of cultured diamonds, providing authoritative "identity authentication" for each diamond . This technical assurance not only maintains market order but also builds consumer confidence.
The laboratory is equipped with high-precision, large-scale testing instruments imported from the United States, Germany, the United Kingdom, and Japan, ensuring data accuracy comparable to that of leading international laboratories. This equipment array is optimized specifically for diamonds, ensuring accurate assessment of cultured diamonds and their grading.
(2) Innovation and advantages
The appraisal certificates issued by GIL International Gemological Laboratory contain multiple anti-counterfeiting technologies and adopt an integrated "testing + logistics + insurance" service for the test samples . The samples submitted for testing can enjoy SF Express's efficient same-city delivery and logistics insurance, covering the entire process and solving the risks in the sample circulation.
At the same time, in the era of trendy fashion items, the laboratory and trendy toy companies have launched co-branded customized certificates , providing professional protection for brand products through exclusive anti-counterfeiting technology.
In addition, online PTZ data service centers have been established in multiple cities. Through multiple data backup mechanisms and encryption technology, the physical security and transmission privacy of detection data are guaranteed, and a complete data security system has been built.
According to recent market research, over 60% of modern consumers are willing to purchase cultured diamond jewelry, citing sustainability, price advantages, and innovative designs as key draws. Compared to traditional diamonds, cultured diamonds offer a 30%-40% price advantage while maintaining the same physical and chemical properties. This allows more consumers to own larger, more stylish diamond jewelry.
Yin Xiuhua, Executive President of the Guangdong International Diamond Chamber of Commerce, stated during the meeting: "Promoting strategic cooperation between GIL International Gemological Laboratory and the Guangdong International Diamond Chamber of Commerce, strengthening talent cultivation and standard setting, continuously improving and perfecting China's cultured diamond industry chain, jointly building China's cultured diamond industry, and telling China's story well, is a groundbreaking initiative."
Chen Faquan, President of the Guangdong International Diamond Chamber of Commerce, stated at the forum: "Cultivated diamonds are not intended to replace natural diamonds, but rather to provide consumers with more diverse choices. This emerging market requires standards, regulations, trust, and innovation. This is precisely the significance of our partnership with GIL International Gemological Laboratory."
During the meeting, GIL International Gemological Laboratory Executive Director Zheng En stated, "The laboratory will utilize advanced identification technology and efficient testing services, strictly complying with national CMA accreditation requirements, and simultaneously establishing strategic partnerships with leading industry players to continuously improve testing processes and service quality, thereby promoting the healthy development of the industry."
As a key chamber of commerce in the jewelry industry, the Guangdong International Diamond Chamber of Commerce brings together over 500 companies from across the diamond supply chain. It is not only a participant in the development of industry standards but also a leader in market trends. The strategic partnership with GIL International Gemological Laboratory demonstrates the importance and expectations that both the chamber and the laboratory place on the emerging field of cultured diamonds.
As their collaboration deepens, both parties will jointly promote the transformation of cultured diamonds from a substitute to a preferred product. Through technological innovation, standard setting, and market education, cultured diamonds will establish a market system and value recognition independent of natural diamonds.
GIL International Gemological Laboratory will work with the Guangdong International Diamond Chamber of Commerce to promote the standardization and transparency of the cultured diamond system. The laboratory will also continuously improve its testing and certification system for cultured diamonds, raising the standards and quality of jewelry testing services. Driven by the seamless integration of traditional jewelry with innovative technologies, and driven by the dual trends of consumer upgrading and sustainable development, the Guangdong International Diamond Chamber of Commerce and GIL International Gemological Laboratory are collaborating to promote the healthy development of the industry.
