Color
The Color Spectrum, which is based on gradual color difference from white to yellow, starts from the letter “D” and goes all the way to “Z”. D, E, F are colorless, “G, H, I, J” are near colorless and it becomes more and more yellow as you go down in the spectrum toward “Z”. As a general rule the whiter the color the higher the value of the diamond. Beyond “Z” we have the fancy yellow colors, or Canary Diamonds. Those diamonds have a separate color spectrum, and depending on the intensity and density of the yellow within the diamond they can be more valuable than even the “D” color. There are some other shades of color, like brown, that can be seen in diamonds. In most cases those would reduce the price of the diamond, depending on the intensity, by up to 50%. The top light brown shades would reduce the price by two grades down in the color. Those shades would make the diamond slightly darker when viewed face up. Some gemological laboratories would state the other shades of color in the diamond on their certificate, but in most cases the only way for a customer to see it is through the side of the diamond on a color paper.
