Accurate diamond grading involves careful observation and consistent evaluation. While the 4Cs provide the basic framework, professional graders also need to understand inclusions, blemishes, fluorescence, polish, symmetry, proportions, and the differences between natural diamonds, treated stones, synthetics, and simulants.
The Advanced Diamond Grading course at IIG is designed around these practical skills. The training includes microscopic evaluation, clarity grading and plotting, color grading from D to Z, fancy-color evaluation, carat-weight estimation, diamond measurement, and practical work with grading instruments.
The course also introduces Indian and international diamond markets and helps participants understand the selection and rejection process based on grading observations.
