The aim of polishing colorless diamonds is mainly to produce a cut stone that is as pure as possible, with a weight as close to that of the rough as possible - in order to maximize yield.
With color diamonds, however, it is not rare that weight will be sacrificed for color. Indeed, it is often possible to strengthen the intensity of the color and the sparkle of the diamond by cutting it, and some passionate diamantaires will sometimes have a stone cut four or five times before being satisfied. The beauty of natural color diamonds is also that they will stand out much more – a 0.05 carat burgundy color diamond can make a gorgeous engagement ring, that is much more impressive than it would be with a white diamond of the same size.
