Judging Diamond Quality
The colors of diamonds are rated with an alphabet grading system that starts with “D” and ends with “Z”. Completely colorless diamonds fall in the “D” and “E” grade, while colored, fancy diamonds are at the other end of the alphabet, at “Y” and “Z”.
The clarity of a diamond refers to whether or not the diamond is clear all the way through, or whether it has tiny flaws and cloudy areas within the diamond stone. It’s actually very rare to have a diamond with absolute perfect clarity and no flaws, but most diamond flaws are not visible to the naked eye and can only be seen under magnification.
