Diamonds that are absolutely clear are the most sought-after and therefore the most expensive. But almost every diamond has inclusions — scratches, trace minerals or other tiny characteristics that can detract from the pure beauty of the diamond. Unless the diamond is graded  F (flawless), there are imperfections.

What Clarity Grade Is Best

We recommend that you select an "eye-clean" diamond — one that has no inclusions visible to the unaided eye. An excellent value, diamonds of this clarity are much less expensive than IF- or F-grade diamonds and typically do not contain visible inclusions that detract from the beauty of the diamond.
