There are two diplomas issues by GIA. Created in 1931, the prestigious GIA Graduate Gemologist (G.G.) diploma teaches jewelers the science and technical knowledge needed to deal with the entire spectrum of diamonds and colored stones. The distinguished G.G. designation at the end of an individual’s name is instantly recognized around the world as the mark of a senior professional in the jewelry industry.

Sometimes the search for the perfect diamond grows into something deeper—a lasting interest in the jewelry and gems. If that’s happened to you, discover how GIA can guide your path toward a Graduate Gemologist (G.G.) or Accredited Jewelry Professional (A.J.P.) diploma, courses in gemology and jewelry arts, and a career in the industry.
