GIA (Gemological Institute of America)

Our mission of ensuring the public trust in gems has driven us for nearly a century. An independent nonprofit, we have proudly protected millions of consumers and educated each next generation since 1931.

Now more than ever, we are committed to serving the public through the relentless pursuit of research, education, and laboratory innovation. And as we look to the future, we stand ready to advance our industry towards a more sustainable tomorrow by protecting the very earth and communities that produce the treasures we love.
