The International Gemological Institute (IGI), one of the world’s largest independent diamond grading and certification organisations, has announced the acquisition of American Gemological Laboratories (AGL). AGL is widely recognised for coloured gemstone analysis and provenance reporting. As a result, this move brings together global scale and specialised scientific expertise under one platform.
The transaction strengthens certification standards across the global gem and jewellery industry. At the same time, it expands capabilities in coloured gemstone research and reporting.
A Stronger Global Certification Platform
The acquisition creates an expanded international certification platform. IGI contributes global market reach and laboratory infrastructure. Meanwhile, AGL brings deep scientific leadership in coloured gemstones. Together, the two organisations aim to enhance trust, transparency, and innovation.
Importantly, the scientific independence and integrity of both institutions will be preserved. This ensures continuity in technical standards while enabling long-term growth.
Tehmasp Printer, Managing Director and Global Chief Executive Officer of IGI, says:
“This is a transformational step for the industry. By combining AGL’s scientific leadership in coloured gemstones with IGI’s global platform, we are building a future-ready certification ecosystem that delivers scale without compromising integrity or science. Together, we are setting a new global benchmark for trust, transparency and consistency in gemstone certification.”
Strategic Alliance and Market Expansion
Through this alliance, IGI will provide AGL access to its global infrastructure. Therefore, AGL will be able to expand coloured gemstone certification services beyond the United States. In parallel, IGI broadens its addressable market and diversifies revenue streams.
Additionally, the move strengthens IGI’s position in the fast-growing coloured gemstone segment. Cross-market integration and expanded research capabilities are also expected to support long-term growth.
Business Continuity and Operations
Operational continuity remains a priority. Chris Smith will continue as President and Chief Gemologist of AGL. Furthermore, the laboratory will stay headquartered in New York and operate independently under its established brand.
No immediate operational changes are planned. Both organisations will continue to deliver the same technical standards and client service levels. However, they will collaborate on developing new tools, reporting formats, and provenance services for evolving global requirements.
Education and Knowledge Leadership
The acquisition also strengthens IGI’s global education initiatives. AGL’s specialised scientific knowledge, research, and teaching methodologies will now be integrated into training programmes. As a result, professionals and students will gain deeper exposure to coloured gemstone science.
Long-Term Investment Vision
Backed by Blackstone’s long-term investment approach, IGI has already expanded its laboratory infrastructure and education initiatives. Now, the same disciplined strategy will support AGL’s continued growth and scientific leadership. This includes expanding its global reach in coloured gemstone certification.
Industry Impact and Global Linkages
Founded in 1977, AGL pioneered country-of-origin reporting for coloured gemstones in the United States. It serves luxury brands, auction houses, manufacturers, retailers, and collectors worldwide.
The acquisition also strengthens linkages between the United States and India. The United States remains the largest market for fine jewellery. India, on the other hand, is a major hub for gemstone manufacturing and certification. Consequently, the combined platform is well positioned to meet rising global demand for provenance, transparency, and consistent certification standards.
Christopher Smith, President and Chief Gemologist of AGL, added:
“This acquisition represents a pivotal and tremendous opportunity for AGL to continue and significantly grow its colored stone services. With the support and backing of Blackstone, as well as the international reach of IGI facilities, AGL will be improving and expanding the standards of integrity, service and products on a global scale across the colored stone and jewellery sectors.”
Dev Shetty, Founder & CEO of Jemora Group and former executive at Gemfields and Fura Gems, served as a strategic advisor on the transaction.
