ABOUT GIA:
Established in 1931, GIA is the world’s largest and most respected nonprofit institute of gemological research and learning.
GIA is the creator of the famous 4Cs of diamond value (color, clarity, cut, and carat weight). It is also the corporate birthplace of the International Diamond Grading System™. Today, GIA’s D-Z color-grading scale and GIA’s Flawless–I3 clarity-grading scale are recognized by virtually every professional jeweler and savvy diamond buyer in the world. The Institute is also known for having developed and patented the first modern jeweler's loupe.
Internationally, the Institute has distinguished itself as the preeminent source of gemological knowledge and professionalism. By extension, the GIA Diamond Grading Report and the GIA Diamond Dossier are considered the world's premier gemological credentials. Diamonds of all shapes and sizes are sent to the Institute from every corner of the globe for analysis and grading. |
