The Gemological Institute of America (GIA) has established an alphabetical grading scale for color grading diamonds. They assigned D as colorless and the best color down to Z which is light yellow. There are two methods normally used to determine the color of a diamond. One is through the use of "master stones" which are diamonds that have been previously graded by the GIA laboratory. The unknown diamond is placed next to the "master stones" under a controlled lighting environment until the closest match is found. The second technique is through the use of a machine called a Colorimeter. This hi-tech instrument takes much of the subjectivity out of color grading. It analyzes the diamond's complete light spectrum to color grade a diamond the same way an experts eye does and to GIA grading standards. Most experts believe that using both "master stones" and the Colorimeter will provide you with the most accurate and reliable results.

However the best color or tint is absolutely none. A color grading scale categorizes the subtle body shade differences from one diamond to the next. A truly colorless diamond allows white light to return to the eye effortlessly, dispersing as a rainbow of colors. When examining a diamond for body color content, you should turn the stone upside down, against a white background so you are looking though the side of the stone. This will eliminate some of the stone’s reflective brilliance so you can better see the true body color.
