A truly colorless diamond is extremely rare; most diamonds possess various degrees of yellow or brown. Small, subtle differences in color can make a substantial difference in price and increasing shades of yellow can reduce the value of a diamond. However, if a diamond is well cut, refraction and dispersion will often disguise certain degrees of coloration. When a diamond is more colorless, it appears brighter and more beautiful. Less light is absorbed by the diamond, and more light is returned to your eye in the form of sparkle. Therefore, color is very important to the overall beauty of a diamond.

Important Color Buying Tips
Most jewelers grade color by using a set of master stones and their eyes. The problem with only using this method is that the jeweler could be off one to three grades in color. At Arthur's, we utilize the latest in technology because eyesight varies from one person to the next and color grading becomes subjective rather than objective; we believe in using the best technology available to accurately grade our diamonds.
We use the Gran Colorimeter. Manufactured in Israel by the leader and innovator in diamond spectral analysis, The Gran Diamond Colorimeter, uses full spectral analysis to color grade loose diamonds from .20 to 10 carats. The Colorimeter measures from D to fancy intense color grades and indicates the tints and hues of the diamond. Using the Gran Colorimeter is another way Arthur's guarantees you the most precise accuracy in grading your diamond.
