The color of a diamond has the second biggest impact on its price, after carat weight. Did you know that diamonds come in every color of the rainbow?
Grading color in the normal range involves deciding how closely a stone's bodycolor approaches colorlessness. Most diamonds have at least a trace of yellow or brown bodycolor. With the exception of some natural fancycolors, such as blue, pink, purple, or red, the colorless grade is the most valuable.
If a diamond does not have enough color to be called fancy, then it is graded in a scale of colors ranging from Colorless to Light Yellow, "D" through "S". A diamond with a "D" color is considered to be colorless. If the color is more intense than "P", it is considered fancy. A fancy yellow diamond fetches a higher price than a light yellow diamond.
The Laboratories only grade diamonds which are unmounted, or "loose", and they do so under special light. Once a loose diamond is mounted on a ring, even the trained professional cannot always tell the difference between, say a "D" color and an "E" or "F" color diamond!
How much does "color" affect cost?
The effect of all the different properties of Diamond on Cost is discussed in more detail in the Cost section. For color, let's take a typical Diamond for an example, and see what happens when we take it through different color grades.
Let's start with a 1.00 carat Diamond of K color and VS1 Clarity. If you move up to an H color, you will pay approximately an extra $1,700 per carat. Move up to F color, the increase will be approximately $1,100 per carat. Improve the color to D and the increase will be approximately $900 per carat.
