Why certificates for diamonds?


Buying a diamond accompanied by a gemological certificate is a pledge of authenticity. The certificate presents the main features of a gem.  Beginning with its form (round or oval), then its dimensions (diameter and height), its color (from D – Z), its proportions (very good – poor), and lastly, its finish (polish and symmetry). These criteria are commonly referred to as “the 4 C’s” (colour, clarity, carat and cut).  The “4 C’s” determine the value of your diamond. Under “learn more”, my site provides a summary for a clear presentation of all the characteristics of the “4 C’s”.  The gemological certificate provides, you the buyer, an objective assessment of the quality of your eventual purchase.
