The International Gemological Institute (IGI), the world’s largest independent gemological laboratory, recently analyzed and graded a 6.18 carat round brilliant-cut, loose stone and established it was a lab-grown diamond at its Thailand location.

RAPAPORT. The International Gemological Institute (IGI) has updated its grading report for synthetic diamonds to include information about post-growth treatments.
The reports will now outline the growth process for untreated chemical vapor deposition (CVD) or High Pressure-High Temperature (HPHT) stones, the lab said Wednesday. They will also specifically indicate those diamonds are “as grown with no indication of post-growth treatment.”
Previously, IGI, which has issued lab-grown reports since 2005, only indicated that synthetic diamonds “may include post-growth treatments to alter color.” Any CVD stones that are not definitively found to be untreated will still carry this description, IGI noted.
“The popularity of lab-grown diamonds has heightened since IGI debuted the industry’s first [reports] 16 years ago,” said IGI CEO Roland Lorie. “As the technology advances and demand evolves, the institute will continue to do right by the consumer.”
