The articles present summaries and discussions of foundational material related to the study, and include information taken from the fields of gemology, physics, optics, computer modeling, and diamond history. Past topics include the 4Cs, diamond optics, Marcel Tolkowsky, the scientific method, and the graphic presentation of information.

“We felt that bringing this diverse information together would give our audience a better understanding of how the proportions of an RBC diamond affect various appearance factors such as brilliance, fire, and scintillation,” said Thomas M. Moses, vice president of Identification and Research Services for GIA. “We’re pleased to make these articles available in an easy-to-download format where they can be printed and referred to as background for future technical articles that GIA will produce on this subject.”
