Diamond cut

The cut of a diamond dictates how well it reflects light and is the most important factor when it comes to a diamonds overall beauty. Even a diamond of top colour and clarity is ugly and dull if the cut is not also excellent. Diamonds are complex prisms designed to reflect and disperse light to generate sparkle, life and beauty.

The three images above show the three simple ways that diamond cut can affect light and in turn the beauty and sparkle of your diamond.

The left-hand image depicts a diamond that has been cut too shallow; this type of shallow diamond cut is very common. When faced with a thin but wide piece of diamond rough the cutter has opted to cut a diamond at maximum diameter. The resulting diamond has a very large diameter for its weight but allows light to pass right through from top to bottom. These stones are particularly ugly as light travels both ways showing off anything in the setting underneath the stone such as a dark space next to your finger or any dirt that is in the setting.

The right-hand image depicts a diamond cut too deep, this type of deep diamond cut is by far the most common way in which a diamond may be cut. The diamond cutter is merely going for maximum weight and profit. For a given weight a deep cut stone has a smaller than ideal diameter. Light travels down into deep diamonds then generally across and out the opposite underside (as pictured). This results in a diamond with either a dull lifeless centre or outer edge.

The central image depicts a diamond cut to correct proportions with triple Excellent GIA certificate gradings, perfectly cut diamonds such as this represent less than 5% of the total diamonds cut in any given year. The diamond cutter has been motivated by perfection. Every beam of light that enters a diamond cut like this is reflected back out through the top of the diamond for the viewer to enjoy.
