International Institute of Diamond Grading and Research

What International Institute of Diamond Grading and Research does

The International Institute of Diamond Grading and Research (IIDGR), operating under the Institute of Diamonds brand, is a London-based diamond grading and research entity founded in 2013 as part of the De Beers Group. The company provides an integrated suite of five core services: standard diamond grading, a specialized Desert Diamond Grading Service for natural diamonds with distinctive tones, Natural Diamond Trustmarking designed to authenticate natural diamonds, industry education programs, and a Report Check verification service. Its core technology combines human gemological expertise with proprietary instrumentation to produce grading reports, with the Natural Diamond Trustmarking service specifically positioned to reinforce consumer confidence in natural diamonds amid growing laboratory-grown competition.

IIDGR serves the global diamond industry value chain, including miners, traders, jewelers, and retailers who require independent grading, authentication, and professional certification. The company leverages De Beers' 130 years of diamond pipeline heritage as its primary differentiator, and operates from a single London office with approximately 11 employees, functioning as a capital-light subsidiary within the De Beers ecosystem. Distribution is conducted directly through its multi-language website (supporting English, German, Thai, Vietnamese, and Chinese) and a client portal, with the institute.debeers.com domain embedding it within De Beers' broader digital infrastructure. No pricing is publicly disclosed, and the revenue model appears to be fee-for-service grading, authentication, and education delivery to industry clients, with the parent De Beers Group likely representing both a pipeline supplier and a significant internal customer.
