The GIA AI clarity system feeds on data from tens of millions of diamonds examined by GIA’s expert diamond graders and “is built on the standards of GIA’s universally recognized International Diamond Grading System™. The system is now in limited use in GIA’s New York and Carlsbad laboratories for the most popular diamond sizes, and the GIA promises to scale the system “to bring accurate and efficient diamond grading to more diamond sizes, shapes and qualities”.
