GIA Opens Lab in Tokyo

The Gemological Institute of America has opened a gem laboratory in Tokyo.

The new lab will offer Diamond Dossier and Diamond Grading Report services for D to Z diamonds up to 2.99 cts. Colored stones and pearls will also be accepted for GIA services.

The facility in Tokyo is GIA’s ninth global laboratory and the seventh outside of the United States.

“Bringing GIA’s diamond grading standards and research-backed lab services to such an important market will serve the public interest by supporting the Japanese gem and jewelry industry,” Tom Moses, GIA senior vice president for laboratory and research, said in a statement. “Our global network of laboratories enables GIA to remain at the forefront of gemological developments and provide the best possible service to our laboratory clients.”
