GIA inaugurates new lab in Dubai

23 february 2024

The Gemological Institute of America (GIA) has opened a new state-of-the-art laboratory at the Dubai Multi Commodities Centre (DMCC).

Located in a custom-designed space on two floors in a premier location in the newly constructed Uptown Tower and operating under the DMCC authority, the GIA Laboratory DMCC is designed for maximum efficiency.

The new GIA location will be limited to catering only to clients operating in the Dubai free trade zones but will soon expand its services to customers from other countries. Services performed in Dubai will be for D-to-Z diamonds weighing up to 3.99 carats.

“Opening a GIA laboratory in the important global diamond center of Dubai is a significant step in expanding our services to advance our important consumer protection mission and meet the needs of the industry,” said Tom Moses, GIA executive vice president and chief laboratory and research officer.

“As an industry leader for research, education, and grading, we are delighted that the GIA now becomes an integral part of the new silk route in the global diamond supply chain, further highlighting the strategic role Dubai plays within it,” said Ahmed bin Sulayem, DMCC Executive Chairman and Chief Executive Officer. “The establishment of the GIA DMCC Laboratory at Uptown Tower adds significant value not only for our free zone members but also for the wider industry, particularly when it comes to speeding up cycle times.”
