This ring is distinguished by its dazzling and highly unique stones. The central 4.01-carat cushion-cut white diamond is superb in quality and certified by the Gemological Institute of America as being both D color and internally flawless. The D-color grading is the highest color grade that a diamond can achieve — these stones are entirely colorless, making them the brightest and whitest of all known diamonds. They are also internally flawless, meaning their remarkable color is unmarred by any imperfection. Partnering with this gem are two Cadillac side diamonds totaling 2.01 carats, so-called for their 5-sided cut that resembles the famous Cadillac logo. The stunning impact of these diamonds is further highlighted by a sleek platinum setting.Download the CertificationClick here to view a video of this item.
