The beauty of a diamond is predominately determined by “cut”. Most people are surprised to hear that a diamond’s carat weight is not a reliable indicator of a diamond’s apparent size. This is due to the most important of the 4Cs – a diamond’s cut. The cut of a diamond determines it’s beauty and brilliance. It is commonly known that diamonds of exceptional cut are very hard to find, given most diamonds are cut to whatever profile will yield the heaviest weight from the rough crystal.
