Color. Many people think of diamonds as colorless. However,
truly colorless diamonds are rare. Many of the diamonds used in jewelry are
nearly colorless with faint yellow or brown tints. These diamonds fall in the
normal color range. A diamond that is said to have 'fine color' has little or no
visible coloration. The less color, the higher the value of the
diamond.
The diamond color scale begins with D and follows alphabetically
to Z. In the D-Z color range, a D color diamond will always be more valuable
than other diamonds, when all other factors (clarity, carat weight, and cut) are
equal.
