While most diamonds appear not to have any color at all, gasses and other elements present at the time they were formed result in slight traces of yellow or
brown in some diamonds. The less color a diamond has, the more valuable it is. Many times the color differences are so slight they can only be detected by
comparing them to other diamonds.
Color differences are measured by the internationally-accepted Gemological Institute of America (GIA) grading scale, and the highest grade for a diamond with
absolutely no color is D and letter grades are assigned alphabetically all the way to Z. The farther away from the letter D a grade is, the more traces of yellow
or brown it appears to have. The chart to the right illustrates the varying grades for Color.
All diamonds sold by Hearts On Fire are in the colorless or near colorless range illustrated here. We select only the best, and in fact less than 1% of all rough
diamonds will meet our criteria for Hearts On Fire.
