The Diamond Color Grading Guide

The colors of diamonds:

The diamond color grading of a diamond is one of few elements that affects its price.

The diamond color grading scale of Diamonds starts from D to Z (D E F G .... etc) and is used to identify the amount of color in each diamond.
(The letters A, B & C are not in use at the diamond color grading scale).
The exact diamond color is determined by a professional gemologist such as our gemologists at Rothem Collection that have years of diamond color grading experience, day by day.

The most colorless diamond color grading of a diamond is determined by the letter "D", while the most colorful diamond grading is determined by the letter "Z".

At the basics, "D" color which is the most colorless grading in the scale, gives the diamond the most high value, while "Z" grading gives the diamond the most lowest value, but not always:

Sometimes "Fancy" color diamonds which are very rare like fancy yellow, Fancy blue, fancy pink (devided also to fancy vivid and fancy intense) etc.. are more expensive than the D color since their color is so intense what gives them an extremely high price such as the "D" color and even more.



Usually people are looking to buy diamonds graded between D color to G color.
H, I & J colors, are considerable as White color which is nearly colorless that still looks very white to the naked eye, and their price is significantly much lower than the most colorless "D" color.

For a certain budget, as low as you go further on the color grading scale (towards Z), The diamond's value goes down so you can afford yourself a better clarity or a bigger carat weight diamond and vice versa.
