GIA Rolls Out Lower-Cost Lab-Grown Dossier

The Gemological Institute of America (GIA) has launched a cheaper dossier report for lab-grown diamonds and broadened the range of eligible goods.

The digital-only document will cost $55 for a 1-carat stone, down from $85 previously, the organization said Wednesday. It will state the lab-grown diamond’s 4Cs but will no longer include information on the growth method or post-growth treatments, keeping the price down. It will now be available for items ranging from 0.15 to 3.99 carats, compared with an earlier cap of 1.99 carats.

“This cost-effective report aligns with our goal of increasing the number of laboratory-grown diamonds with GIA reports in the market to protect consumers and ensure their trust in gems and jewelry,” said GIA CEO Susan Jacques. “We are tailoring our reports to focus on the information consumers and retailers find most important — the 4Cs and whether the diamond is natural or laboratory-grown.”

The GIA confirmed that it was refreshing the report — called the “Laboratory-Grown Diamond Report – Dossier” — late last year, but didn’t say what the new price would be. Specifying the growth method and post-growth treatments is an expensive process, it added.

The GIA will continue offering its more detailed lab-grown grading reports, which include growth method, post-growth treatments and a plotted clarity diagram. These reports are available for D to Z lab-grown diamonds weighing 0.15 carats or more.
