How to evaluate a diamond color?
There are color differences in white diamonds, from one grade to the next subtle one. A mounted diamond has a low chance of seeing the differences between the grades. Always remember that a mounted diamond can’t have an accurate grade color. However, even a non-diamond expert can spot the color differences of the stones in an unmounted diamond when viewed properly.
Due to the dispersion and high brilliance of the diamonds, the color grade can’t be accurately determined by just having a look on the stone from the top, or face-up, position. The best thing to do in observing the color is to examine the stone by the pavilion with the table down. You can do this by making use of a flat white surface such as a grading trough, a white business card, or the Gemological Institute of America (GIA). Then, you can view the stone with the pavilion side down and the culet that is pointing toward you.
What is diamond body color?
When we talk about the diamond body color, we talk about the huge amount of brown or yellow tint that is seen on a white or colorless diamond. Countries like America and Russia are grading most of their white diamonds in an alphabetical scale starting from the letter D, meaning it is the rarest, finest, and most colorless diamond that continues down to letter Z. Each letter next to the letter D means an increased amount of brownish or yellowish tinge to the body color.
Understanding the diamond body color is easy. You just have to keep in mind that the letters closer to the letter D indicates a whiter diamond while the letters closer to the letter Z indicates a more yellowish or brownish diamond.

The colors M to Z show a progressive more tint color and have a definite yellowish or brownish cast.
