Color refers to the presence or absence of color in white diamonds. Acting as a prism, a diamond can divide light into a spectrum of colors and reflect this light as colorful flashes called fire. Just as when looking through colored glass, color in a diamond will act as a filter, and will diminish the spectrum of color emitted. The less color in a diamond, the more colorful the fire and the better the color grade. Diamonds are assigned color grades by comparing them to diamonds with color grades which have been certified by the GIA as master color comparison diamonds. The GIA grades color alphabetically from D (totally colorless) to Z (yellow). Color differences are very subtle and it is very difficult to see the difference between say, an E and an F. Therefore, colors are graded under controlled lighting conditions and are compared to a master set for accuracy. When determining the color of a diamond, it is crucial to see the diamond unmounted. *The different colors could be presented in a chart or table - each letter the color it represents. |
