Upon completion of this course, students will have a comprehensive understanding of the chemical nature of diamonds, how they are formed, classified (colourless and fancy coloured), mined, processed and cut, the unique properties that allow them to be separated from other colourless gemstones, and how they are graded.

You will learn all about the 4 C's (colour, clarity, cut and carat weight) and how they are measured and assessed. We will also compare the various 'Cut' criteria for the Gemological Institute of America (GIA), the American Gem Society (AGS), Hoge Raad Diamant (HRD), International Gemological Institute (IGI), the European Gemological Laboratory (EGL), and Accredited Gem Appraisers (AGA) and explain how the estimated weight of a 'mounted' gemstone is calculated.
