|Diamond Color Grade|
The Experts at Work
It’s truly fascinating to see our skilled diamond graders at work analyzing a diamond’s color.
Using a master set of diamonds specifically chosen based on their range of color, the graders pick up the diamond they are grading with tweezers and place it next to the individual diamonds in the master set. The diamond grader then makes a skilled judgment call — something that requires good eyes and extensive experience.
Unmounted Diamonds Provide a More Accurate Grade
Diamonds not in a setting and, therefore, loose are called unmounted. That’s how we grade ALL our diamonds. We do this so that the color is not influenced by the metal of the setting. For example, a diamond set in a yellow-gold ring could appear more yellowish in tone than one in a white-metal mounting. By grading loose diamonds, we get the best and most accurate read possible.
An Easy to Understand 0 to 10 Scale
The American Gem Society Color Grade indicates where a diamond's color falls on a scale that runs from 0 (colorless) to 10 (light yellow or light brown). Most labs grade based on using D as the best color, down to Z. We felt we could give a more accurate and specific description of the color of your diamond if we used a numeric scale. This way, you will have a better understanding of its color. If you look at the scale on this page, you can learn what each numerical grade means in term of color.
