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.

The Fancy Color Diamond Book: Facts and Secrets of Trading in Rarities is a 231-page hardcover that combines the imagery of a coffee-table book with facts about colored diamonds. The Fancy Color Diamond Book explores the range of fancy colors and discusses grading, clarity, and the role of fluorescence in determining value.

Solitaire Setting

Solitaire Setting is a popular diamond engagement ring setting. The head secures the diamond. The prongs allow the diamond to catch the most light. A four-prong setting shows more of the diamond, but a six-prong setting is often more secure.

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.
