COLOR

A truly colorless diamond is extremely rare.  Most diamonds possess varying degrees of yellow or brown, and small, subtle difference in color can make a substantial difference in value.  If a diamond is well cut, its refraction and dispersion often will disguise certain degrees of coloration.

The diamond color-grading scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z.  Color grades are determined by comparing each diamond to a master set.  Each letter grade represents a range of color and is a measure of how noticeable a color is.  Diamonds are valued by how closely they approach colorlessness – the less color, the higher the value.

Although increasing shades of yellow can reduce the value of a diamond this does not necessarily reduce its beauty.
