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.

Brilliance Through Diversity – GIA’s Inclusion & Diversity Philosophy

At GIA our mission is to protect the public trust; therefore, we must reflect the public. We believe that inclusion and diversity go hand in hand. Our culture is one in which every employee feels a sense of pride, safety and belonging; valued for who they are and the unique background, experiences and perspectives they bring to the Institute. To succeed, each of us must live our values of leadership, teamwork, respect, integrity and results, and hold ourselves and each other accountable, not just within our Institute, but within the global gem and jewelry industry. At GIA we assume positive intent as we listen with an open heart and an open mind; committed to continuous learning and personal growth. Not only because it’s the right thing to do, but because this is who we are.

Sustainability is Critical for GIA, Our Future and Our Industry
Developing a sustainability strategy is an important step towards supporting our mission to ensure the public trust in gems and jewelry and becoming a more resilient organization, with a positive impact on the world around us.

Our environmental, social and governance (ESG) strategy has enabled us to determine where to focus our efforts in order to have the greatest impact, to identify where we want to lead and to set relevant targets against which to measure our performance and progression.

Materiality Analysis
To inform the development of our sustainability strategy, we conducted a double materiality assessment in 2022. This process enabled us to identify and assess our most significant current and potential impacts relating to environmental, social, economic and governance-related topics. Through engagement with a wide variety of stakeholders – internally and externally – using surveys, interviews and workshops, we assessed the impact of wide-ranging topics across two dimensions, using established impact assessment criteria:

  • Inward impact – the impact of sustainability-related topics on GIA
  • Outward impact – GIA’s impact on sustainability-related topics on the world around us

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.
