Mission & Governance

Mission Statement

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 Board of Governors

The GIA Board of Governors is the steward of the public interest.  The board helps direct the strategy of the Institute to ensure that the mission and vision of GIA are followed in all decisions; that the reputation of GIA is preserved and continues to grow globally; and that the financial goals of the Institute are met.

Each governor offers a unique perspective, based on their professional experience in retail, research, education, finance, law, manufacturing and other areas; several have extensive international experience.

GIA’s first advisory board of retail jewelers was organized by Robert Shipley in 1932 to garner support for gemological training. Having a board of directors is one of the requirements for a public benefit nonprofit organization in the United States. All of GIA’s global activities fall under the same governing concept.
