IGI Earns Lab Grown Diamond Certification from ISO

Accreditation marks the Institute as the world’s first laboratory to receive this achievement and reinforces dominance in lab-grown diamond market

New York (March 25, 2021) — The International Gemological Institute (IGI) announced it has become the first laboratory in the world to receive the ISO 17025 accreditation for lab-grown diamonds – the single most important standard for calibration and testing laboratories across the globe – that is achieved after going through stringent checks and rigorous audits of jewelry. Obtaining this certification further showcases the Institute’s expertise in gemological services and reinforces that consumers can trust jewelry that has been evaluated by the world leader in lab-grown certification.

“IGI previously earned an ISO certification for natural diamonds and now achieving the same accreditation for lab-grown diamonds speaks volumes about the work the Institute does,” said Tehmasp Printer, managing director, IGI. “This milestone showcases our competency in gemological services and solidifies IGI’s prestige in the lab-grown space.”

“This is a landmark accomplishment and IGI is proud to be the first recipient of this accreditation, especially as the Institute pioneered lab-grown certification in 2005,” remarked IGI CEO Roland Lorie. “As the vast majority of lab-grown diamonds in the United States, India and China are certified by IGI, we look forward to sharing our first-class accuracy and efficiency in reporting with our global customer base.”

This standard is awarded to companies and laboratories where testing occurs and forms part of the product certification. Directly, the designation observes two main sections: quality management requirements, such as document control and corrective action, and technical requirements that measures competency of staff and equipment calibration. IGI currently maintains two additional accreditations from ISO – 9001, which recognizes quality management, and 17025 for diamond certifications.

“We keep the end consumer top-of-mind at every stage of our work,” continued Lorie. “We share this prestigious recognition with our customers and pledge to continually be a resource of trustworthiness and confidence for the industry.”
