The clarity grade of a princess cut diamond is based on how many and how severe the imperfections are on a diamond. It’s harder to see flaws on smaller princess cut diamonds than larger ones, so you can get away with purchasing a lower clarity rating on smaller diamonds while maintaining an eye-clean appearance. In addition, because princess cut diamonds are brilliant cut and have a lot of sparkle, they hide blemishes fairly well.
Evaluating clarity in princess cut diamonds is subjective because each consumer has their own standard for clarity. Some may be perfectly comfortable with inclusions as long as they cannot easily see it, but other may insist on a more technically flawless appearance. The clarity chart below provides general guidelines for picking a clarity rating for your princess cut diamond, based on your inclusion tolerance. Please note that the ratings in the Clean to the Naked Eye column assume that your jeweler will check to ensure it is actually eye-clean. For example, every time a customer purchases a princess cut engagement ring from us, we send a gemologist to check and make sure the diamond is “eye-clean” and inform the customer if it isn’t. If you want an eye clean stone, make sure you ask your jeweler to do the same.
