The 4C’s of evaluating and valuing Diamonds

When you intend to purchase a diamond it is vital to ensure that it is genuine. The best way to determine the quality of a diamond is by using the “4C’s” (cut, clarity, color and carat) evaluation. These are the main factors used to find out the beauty and value of a diamond.


Diamonds come in different colors from clear to all colors of the rainbow. Colorless diamonds cost more than the colored ones and the size of the stone also determines its carat and hence price. By placing the diamond on a table and having very specific conditions of background, distance and lighting, you can be able to observe the color scale thus tell the quality.


Carat refers to the weight of the diamond and it is directly related to its size. However, it is not always true that the size of the diamond is directly proportional to its weight. You may be deceived by the relationship between how big a diamond appears and its actual weight. A diamond with a shallow cut will look larger than a well-cut one of a similar weight since its diameter will be larger.


The measure of the surface and internal characteristics of a polished diamond is the way that is used to determine the clarity. This means observing the blemishes on the surface and the kind of inclusions (internal characteristics) a diamond has. A diamond with no visible blemishes or inclusions is rare and hence more valuable.


There are two elements one should consider as pertains to the cut of a diamond. They are namely proportion and finish. The finish is further sub-divided into polish and symmetry. The precision, artistry and care used in cutting a diamond bring out its full potential.
