A big warm welcome Jasper Paulsen who has done a publicly available web version of Tolkowsky's "Diamond Design" which also has a running commentary. He makes a very interesting claim. "Contrary to popular belief, Tolkowsky's model actually provides a range of ideally cut diamonds. Tolkowsky explains how the best crown angle and table size depend on the pavilion angle. I have calculated a table of these proportions. They agree with the results of
the Moscow State University (MSU)
and Gemological Institute of America (GIA) studies." Here is the link http://www.folds.net/diamond/index.html
