Founded in New York City in 2005 by Mark Gershburg and Debbie Azar,[4][5][6][7] GSI's laboratory division provides diamond and gemstone grading and identification services as well as gemological research, and a variety of educational programs for gemological professionals.[2][4] GSI also acts as a resource of gem and jewelry information for trade press, global media organizations and the general public.[2][4]

GSI’s worldwide headquarters is located in New York City’s Diamond District. GSI has laboratories in India (Mumbai, Surat and Thrissur); the Israel (Ramat Gan); UAE (Dubai); Belgium (Antwerp); Botswana (Gaborone); and Hong Kong.[8]
