International Gemological Institute (IGI), one of the world’s largest independent diamond grading and certification organisations, announced the acquisition of American Gemological Laboratories (AGL), a global leader in coloured-gemstone analysis and provenance reporting. The move strengthens IGI’s presence in the fast-growing colour segment while adding AGL’s scientific depth and provenance expertise to its platform.
Under the agreement, AGL will continue to operate independently from its New York headquarters, with Chris Smith remaining President and Chief Gemologist. IGI will provide global infrastructure and market access, enabling AGL to expand services beyond the US while maintaining its established standards and brand identity.
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.”
Both organisations will collaborate on new reporting tools, provenance services, education and research initiatives. Supported by Blackstone’s long-term investment strategy, the combined group aims to deepen laboratory capabilities, broaden training programmes and enhance trust and transparency for retailers, manufacturers and collectors worldwide
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 coloured 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 coloured stone and jewellery sectors.”
Dev Shetty, Founder & CEO of Jemora Group and former executive of Gemfields and Fura Gems, served as a strategic advisor on the transaction.
