The Color Spectrum

  • Diamonds come in a wide range of colors, from white or colorless to black, including the most important colors: yellow, pink, blue, green and red.

  • Since 1954, the Gemological Institute of America (GIA) has graded colorless or white diamonds from D (colorless) to Z (a light yellow or brownish shade).

  • In the mid-1970s the GIA created a color grading system for colored diamonds. This grading system does not rely on letters of the alphabet, but on descriptive language indicating the amount of color saturation in the diamond.

  • In the mid-1990s the GIA enhanced its color grading system, resulting in increased awareness and value of all Fancy Color Diamonds.
