Diamond Color Scale
Natural colored diamonds are formed in the same way as white diamonds with the only difference being the color of the crystal. The color is believed to have occurred in the forming of the crystal millions of years ago by nitrogen or other elements being trapped in the crystal lattice. Natural colored diamonds come in all shades, hues and colors of the rainbow, with the most common and inexpensive colors ranging from brown to yellow.
If you’ve tried on a diamond, thought about buying a diamond, or actually purchased a diamond, then you’ve most likely been confronted by the “Four C’s,” cut, color, clarity and carat weight. Diamond sales people will put a diamond in front of you and immediately start talking in terms of “D color, SI1 clarity” or “G color, VVS2 clarity” and that is when most people’s eyes glaze over. While the Four C’s are relatively simple concepts used to describe a diamond’s attributes, most people don’t understand the language of diamonds. This series will attempt to simplify those concepts.

In general, when you mention diamonds, the first picture that comes to mind is the colorless diamond in every jewelry shop window. However, diamonds come in every color of the rainbow. The colorless diamond is by far the most common diamond found in nature with red diamonds being the most rare.
The Color Scale
The color scale used in grading diamonds was developed by the Gemological Institute of America (GIA) in 1952 to standardize the grading of color in the diamond industry. Prior to the adoption of the GIA scale, jewelers used proprietary scales to determine color in diamonds. This became very confusing for consumers who would go to one jewelry shop and be shown a “white” and “eye clean” stone and then go to the next jeweler and see a “AA” color and “3” clarity. Without being able to make an apples-to-apples comparison, how could the consumer be sure they were making the right decision? Enter the GIA. In an effort to disassociate the GIA scale from existing scales, the GIA began its color scale with D and ended it with Z. Most diamonds for sale in the average retail store stop somewhere in the K-M range.
