Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Ideal cut refers to the angles and proportions of a diamond that satisfy very precise mathematical formulas. The result is that the the ideal cut diamond internally reflects most light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing ideal-cut diamonds higher on the quality pyramid than deep or shallow-cut diamonds.
Color H color diamonds are near colorless. H color may be somewhat noticeable when compared to diamonds of better grades, but this grade offers excellent value. Its very faint tint will only be noticeable to a trained gemologist. Such diamonds look beautiful in platinum and white gold and offer outstanding value.
