Valuing a diamond: size and color

The four characteristics that determine the value of a diamond are called “4C’s” and are: Cut (size), Color, Clarity (clarity) and Carat (weight or carat).


Although there are many possible cuts, the most common to get the most out of diamonds is the brilliant cut. If the cut of the diamond is not too good, part of the light is not reflected and it loses part of its attractiveness.  

Colour The color of a diamond greatly influences its beauty and price. The more colorless, the better quality.



The most widely used color scale today is that of the GIA gemological laboratory, which is the one used in most jewelery stores. This scale orders the color of diamonds from the letter D (colorless) to Z (yellow or brown).
