What makes a diamond so valuable is its unmatched beauty. Without its sparkle and shine a diamond would appear as just another nice looking gem stone. The colour and clarity of a diamond are both major contributors to its brilliance but it is the Cut that changes the appearance from a shimmer to shine.
Diamond Cut refers to the way that a rough stone is polished in order to reveal its many facets. The intensity of brilliance and beauty embodied in the diamond are revealed through the expertise of a skilled diamond cutter. It is this master craftsman who diligently polishes the diamond, one facet at a time. Ideal proportions, finish and symmetry are the desired end result of the cutter. Poor symmetry will result in misdirected light after it enters then exit the stone.
Cut refers to the reflective qualities of the diamond and it is perhaps the most important of the 4Cs.
Cut Quality is graded as follows:
Very Good Cut
The four attributes of diamond quality (The 4C's) are all of extreme importance. However, as the single attribute that man has the ability to perfect on his own, a diamonds Cut must be done with patience and care. It is quite amazing when you consider how much concentration and attention that must be given 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. Its 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.
Cut vs. Make
No two rough diamonds will ever be exactly identical. The theory behind Cutting a diamond is the skill of how to derive the best finished product from any rough stone.
By definition, the Cut is the prearranged faceted arrangements of the diamond.
Since it is through the Cut that the finished product is created, how professionally the faceted arrangement is organized is referred to in the industry as the 'make' of the diamond.
People often confuse the Cut with the shape of a stone. However, even though they are closely related, they are not completely the same. The diamond Cut refers to the style used to form the stone regardless of the diamonds shape. The style is created by using different forms of symmetry, polish and geometric proportioning between the many facets, otherwise known as the make. Any diamond shape can have more than one different diamond cut. The style is in every sense of the word both a science and an art
Common Diamond Shapes
The diamond shape refers to the geometrical form of a finished stone. The two main styles used to cut down a stone are 'Round Brilliant' and 'Fancy Shapes'. Today, many variations of these two styles have been developed. However, the general idea still remains.
