Color is the first subject, we are going to talk about. Diamond scale is not difficult at all. First of all, it’s easy to understand because the scale goes in the alphabetical order, we just begin our scale from letter “D” as the highest color. Why do we start with “D”-? Because A, B, and C were already used for other definitions in diamond industry. Now, we can divide the whole scale into 3 groups:
D,E,F - Colorless
G,H,I,J - Near Colorless
K,L,M,...Z - Light Yellow
It is not difficult, is it right? Most of the diamonds have yellow tints of color, which are caused by the trace of nitrogen inside the crystal lattice of diamond. The more nitrogen is in the diamond – the yellower it is and the price is lower. The less color is in the diamond – the rarer it is and the price is higher. According to it, we grade diamonds from D to Z colors scale. From absolutely colorless D color to the strongest tint of Z color grade.
