Almost anywhere in the world, someone is using knowledge acquired from GIA to create, to make, to evaluate, to research, to improve

Located at GIA’s World Headquarters and Robert Mouawad Campus in Carlsbad, California, the Richard T. Liddicoat Gemological Library and Information Center houses a growing collection of over 57,000 volumes, 300 international journals, 150,000 photographic images, over 1,800 videos and DVDs, and the Cartier Rare Book Repository and Archives. Whether in person, by phone, e-mail, or fax, the Library staff answers the questions of scientists, jewelers, gemologists, students, researchers, authors, and the press from every corner of the globe, providing “ready reference” on a wide range of topics including treatments.
