A clarity enhanced diamond is a natural diamond! Not created or man-made. Basically a CE diamond is a diamond that originally had inclusions that were visible to the naked eye, but with modern techniques the inclusions are "corrected" so the inclusions are masked, making them not visible to the naked eye! The enhancement process has the same optical properties as a diamond so light travels through the stone as if those original inclusions weren't there, allowing the diamond to sparkle and scintillate as fiery as a GIA certified diamond of "comparable" grade! The process is lifetime guaranteed and we can forward you the study GIA has done on CE diamonds, you will love the results!
