GIA exists to protect all purchasers of gemstones, by providing the education, laboratory services,research, and instruments needed to accurately and objectively determine gemstone quality.

A nonprofit institute, GIA’s mission is to ensure the public trust in gems and jewelry by upholding the highest standards of integrity, academics, science, and professionalism through education, research, laboratory services, and instrument development. GIA attained its leadership role through decades of integrity and ingenuity, and everything we do is still driven by this mission.
