To avoid such confusion, numerous organizations, often called laboratories or institutes, have been established to offer a grading service to jewelers, diamond collectors and other figures that require an evaluation of diamonds that they are either going to sell or buy. Since the price of diamonds is quite high, such a service has become essential. Today, we have quite a large number of these organizations. One aspect that all of these organizations have in common is the fact that they all rely on the four C’s that are used to inspect a diamond and to determine its quality – this, in turn, can then be used to calculate a more accurate and fair selling price for the particular diamond.

These organizations have professionally trained appraisers that have the ability to closely inspect diamonds under a special magnifier that is used specifically for the appraisal of a diamond. While inspecting the diamond, the appraisers will look at numerous factors, such as whether the diamond contains any cavities, inclusions or blemishes; how well the diamond has been cut; whether the diamond is completely colorless or contain hues of colors and more. They also weigh the diamond to determine its weight in carats. After this process has been conducted, the appraiser issues a certificate that should always accompany the diamond.

Important Data On A Diamond Certificate

Once you visit a jeweler and request a diamond certificate, there are a few essential data points that you should look at before you buy the diamond. First, consider the four main qualities of the diamond and remember that many of these qualities do not only contain a fundamental rating, but also additional data that should also be taken into consideration. For example, while the “cut” grade of the diamond might be marked as “ideal”, it is important to also look at the subsectors of the “cut” grade, which should include “table %”, “depth %”, girdle size and more.
