Diamond Cut

Cut is a feature that reflects the beauty and brilliance of the diamond, and usually determines both the value and price. A key factor when making a diamond purchase is cut, as one may decide to compromise on clarity, size or color, but never on the cut. You must always ensure that you have the most ideal cut diamond.

In 1919, a Belgian Mathematician, Marcel Tolkowsky, formulated the exact proportions of how a round diamond should be cut, in order to maximize the light reflections of the diamond.

Over the years, with advances in modern technology, based upon Tolkowsky's formula, the ideal range was developed.

Two diamonds of the same shape and carat weight may still appear different in size based on the cut proportions. A deeply cut diamond has a greater proportion of its total weight "hidden" in the depth, resulting in a smaller diameter than a well cut diamond. These differences are usually small, but noticable. A well cut diamond may even have a slightly lower carat weight than a deeply cut diamond, yet still have a larger diameter, making it appear larger in size.
