At GIA, we believe every gem has a story — formed deep within the earth and revealed through science. For nearly 100 years, we’ve been bringing those stories to light through research, discovery and education. As a nonprofit, our mission is to ensure confidence in gems and jewelry by blending innovation, knowledge and science. From creating the 4Cs of diamond quality to inventing tools used worldwide, we make learning an adventure and turn discovery into truth. We don’t buy, sell or appraise gems. Instead, we provide trusted reports, education, and insights that help people — from industry professionals to everyday consumers — make informed decisions with clarity. This is GIA: where curiosity fuels innovation, knowledge builds confidence and science inspires a world of trust.
