Design correct Tolkowsky's rounding errors, and show how the best crown angle and table ratio depend on the pavilion angle. He estimated the best proportions for cutting round brilliant diamonds. Cultural Orientation Resource Center. He wrote that this angle "gives the most vivid fire and the greatest brilliancy, and that although a greater angle would give better reflection, this would not compensate for the loss due to the corresponding reduction in dispersion.". Ass is the Java 2 program that calculated the bold curves in Figure.

Where, however, it was found that the accuracy of the results would be impaired without the introduction of more advanced mathematics, these have been used, and graphical methods have been explained as an alternative."
