Most 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. Diamonds outside the normal color range are called fancy-colors and come in about any color you can imagine. Before GIA introduced the GIA D-Z Color Grading Scale, a variety of other symbols were loosely applied throughout the industry.
