In a previous post I made a case for Cut being the most important of the four C’s.  The second most import C is color.  Color is one of the easiest things to notice about a diamond.  You might not know the color grade of a diamond but you will notice right away if it looks yellow or not.  A chemically pure diamond has no color and is referred to as colorless.  This represents diamonds that fall in the D-F color range. As a point of reference, the diamond color scale starts at D (colorless) and goes to Z (yellow but not Fancy Yellow – more on Fancy Color diamonds another time).

Most people tell me that they want a diamond that doesn’t show any yellow.  If you feel that way too then you want to choose a diamond with a color of H or higher.
