Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds of premium cut proportions are almost as good as ideal. Most people will not be able to distinguish an idea cut from premium. Less diamond material is lost in the process of cutting thus making the diamonds less expansive then ideally cut ones. In short premium cut reflects almost as much light as the ideal-cut, but for a lower price.

G-color diamonds are the most rare of the near-colorless diamonds. Its extremely faint tint will only be noticeable to a trained gemologist.

Such inclusions may be visible to an unaided eye depending on their location. SI2 clarity diamonds of G or H color look nearly perfect when mounted. For those looking for near perfection these sure come close.
