CUT
The traditional 4 C's ideology is simply a take-off point for the love diamond. By way of review, here in essence is what the basics are all about. A diamond's brilliance depends largely on how much light is reflected back to the eye. This is determined by the cut. Each facet of the diamond must be cut to precision - i.e. ideal proportions, perfect symmetry and perfect polish, hence it is the most important of the 4 C's.
The Love Diamond is consistently cut to radiate exceptional brilliance, no matter what its clarity grade may be.
