Ideal Cut Proportion |
|
To produce maximum brilliancy, light-dispersion and scintillation, it is necessary to compute mathematically the best angles and proportions to cut a diamond. Marcel Tolkowsky published such a computation in 1919 in a book entitled Diamond Design. This set of angles and proportions came to be called the "ideal" cut.
In an Ideal Cut every facet has to be placed at an exact angle and the proportions are so calculated as to create an "ideal" balance between maximum brilliance (the return of the light to the eye) and dispersion or "fire" (the prism effect that separates white light into its spectral colors).

The figure shows the principal elements of the "ideal" cut as calculated by Tolkowsky. |
