Fancy Colour Diamond Cut

What is the cut of a diamond?

Some of the most famous diamonds in the world have such a pleasant appearance that not to admire their magnificence would be considered a sin. What makes diamonds so valuable is their beauty. Without the sparkle and shine one expects to see a diamond will appear as just another nice looking gem stone. Granted, the colour and clarity of the diamond are both major contributors to the brilliance, but the cut is precisely what changes the stone from a shimmer to shine.

The four attributes of diamond quality known as the 4Cs are all of extreme importance. However, as the single attribute that man has the ability to perfect on his own a diamond cut must be done with patience and care. What is so amazing to consider is the concentrated attention that someone must give to each and every stone.

The cut of the stone is directly connected with all the other characteristics of quality. How the diamond is cut will influence the diamond carat weight. The geometric proportions will affect the diamond colour. The art of polishing can even help rid of external blemishes and therefore naturally enhance the diamond clarity. 

Depth of the Diamond

The cut of the diamond has much to do with the overall appearance of the stone. In fact, if a full certificate is supplied with the stone the cut grade is included within the many diamond characteristics.

Along with all the various dimensions of the stone that are noted, the depth of the diamond plays a very significant role in the overall appearance.

The image above displays specifically what affect diamond depth has on the appearance of the diamonds shown. From left to right: a 0.45ct stone with a 28% depth, a 1.24ct stone with a 46% depth, 0.56ct stone with a 58% depth, and a 1.14ct stone with a 70% depth.

Light Within the Stones

In a colorless stone, since the objective is to remain as colorless as possible the amount of time light remains within the stone must be condensed. However, with Fancy Colour Diamonds the longer the light remains within the facets of the stone the more the colour is shown.

The cut in the Leibish Prosperity Pink enables the light to remain within the facets of the stone and shows an excellent vivid purplish pink colour.

The diamond cut is such a critical diamond attribute because how the diamond is cut and polished directly affects the sparkle and brilliance of the stone.
