Cut Of A Diamond

The cut of a diamond describes how well-balanced the proportions of a diamond are and how these surfaces, or facets, are arranged to produce sparkle and brightness. What is, for instance, the ratio of the diamond’s depth to its diameter? The diamond’s beauty and price are determined by these minute but crucial elements.

The cut of a diamond not only refers to the diamond’s shape, it also refers to how effectively the diamond returns light back to the viewer’s eye. A well-cut diamond will appear very brilliant and fiery, while a poorly cut diamond can appear dark and lifeless.

How Diamond Cut Affects Price?

Diamond pricing involves a very complex mechanism that revolves around many different factors. In fact, the cut of a diamond can drastically increase or decrease its value. In general, you can expect the diamond’s cost per carat to increase as the cut quality improves. This is because more rough material has to be removed in order to achieve better cut proportions and symmetry when polishing the facets.

If you don’t know yet, diamonds are inherently priced by their carat weight. When more rough material is removed, the loss in carat weight for better cut quality has to be compensated with higher prices.
