It is definitely true that the beauty and brilliance of an ideal cut diamond will be able to mask the internal imperfections from being visible to the naked eye, even in the case of a lower clarity graded diamond.
The beauty of this, is that it affords you the ability to spend less money on a lower clarity grade, while still buying a diamond that faces up "eye-clean" with incredible brilliancy!
Here is a SuperbCert Signature Ideal Diamond that we sold to a customer.
The diamond is a GIA certified, I1 clarity graded stone that actually faced up eye clean as a result of its beauty and light performance!!
