Diamond Design by Marcel Tolkowsky, a Study of Brilliance and Dispersion for Round Diamonds

The book Diamond Design by Marcel Tolkowsky was written in 1919, as an analysis of diamond proportions for the purpose of determining the exact proportions which would produce optimum brilliance and dispersion in a round brilliant cut diamond.  The Tolkowsky family has contributed a lot to the advancement of diamond cutting over the years, I think that this is an article which you’ll enjoy reading and it will contribute greatly to your understanding of diamond proportions and the proper use of the term Tolkowsky Ideal Cut as you search for diamonds. Read my article on Tolkowsky Ideal Cut Diamonds.
