We’re a school. We’re a laboratory. Teachers, scientists, librarians, writers, photographers, and many others work at GIA all over the world. Our purpose is to study gems and jewelry, and to teach about them – so that everyone can be informed.
People come from all over the world to study at GIA. Many want to work in the gem and jewelry industry. We teach them how to identify and evaluate gems. And we teach them how to design and make jewelry.
Our library is the largest gem and jewelry library in the world. We have over 38,000 books on gems and jewelry, with the oldest book dating back to 1496. We also collect and preserve mineral specimens, jewelry, gem art, and gemological equipment.
