Diamond Color
Diamonds range in colors from all across the spectrum. The deeper the color within the stone, the more rare and valuable it is. Although, a superbly colorless stone with no taint of yellow or any other color is a very valuable find. These stones are considered "fancy diamonds" because of their many "fancy" colors. If a diamond is not considered gem colored, meaning fit for the jewelry market, it is used in the industrial world. Usually, these diamonds are tinted too yellow to be considered a good colorless stone but not in enough intensity to be considered valuable, or a yellow diamond. The GIA and AGS labs use a 0 to 10 point scale along with an alphabetical scale to chart colorless diamonds. The stones that range from D, E, and F are colorless and don’t have any or much yellow tint to them. Colors G, H, I and sometimes J usually won’t show color if placed in a jewelry setting. Keep in mind that emerald cut diamonds show color more often than other cuts because of their large table area. It is usually a bad idea to buy a diamond from G and below in an emerald cut although exceptions are possible. Round brilliant or super-ideal cut stones are known to show slightly less color than the grades they are given and therefore can be a good money saver. Florescence is also an important factor to look at when purchasing a colorless diamond. Blue is the ideal florescence color.
