Advanced Retail Diamond Buying
By David Bellman, G.G.
Welcome to Cool School™
This Cool School video course was designed to help educate consumers in the areas of diamond grading and evaluation. You will watch video tutorials written and produced by David H. Bellman, GIA Graduate Gemologist with over 35 years of diamond grading experience. You will learn invaluable information that will save you hundreds if not thousands of dollars on your diamond purchase.
In about 90 minutes, you will learn the techniques used by professional diamond graders to determine the actual grade and value of almost any diamond. When you complete this course in Retail Diamond Buying, you will likely know more about diamond grading than the majority of people selling diamonds.
This program is free and was designed to bring transparency to an often confusing and unregulated diamond grading system. In the future, additional courses will be added addressing many other areas of the jewelry industry.
