Although most gem-quality diamonds when seen alone appear to be colorless to the untrained eye, there are subtle differences in shade. Color in diamonds results from traces of other elements which mixed with carbon during the diamond's formation. Diamonds with no traces of body color are extremely rare.
To determine a diamond's true color, the diamond is viewed from the side under balanced white light. It is compared to diamonds in a "Master Set" whose colors have been predetermined by the Gemological Institute of America (GIA). Our diamonds are color graded in an accredited gem laboratory using a special diamond light developed for color grading. A color grade is then assigned according to the diamond's deviation from the truly colorless diamond.
