About the CPD course

The De Beers Polished Diamond Grading Course is an in-depth study of the diamond pipeline. The course is split into two component parts. The first involves distance learning study using 11 textbooks especially designed by De Beers; each one devoted to a specific aspect of diamonds. Topics include diamond origins; physical properties; exploration; mining; cutting and polishing. Also covered is theory of polished diamond grading using the 4Cs (Carat; Colour; Clarity; and Cut). On completion of the distance learning section students then attend a 1 week laboratory experience. Here students will develop their practical grading skills under the guidance of De Beers’ experts; with a practical assessment at the end of the week.
