Explanation of Cut, Color and Clarity of This Diamond
Cut Quality The ideal cut diamond is a very precise mathematical equation, where diamond proportions and angles are cut to optimize the diamond's superlative optical properties, in particular it's high refractive index and color dispersion, to create a diamond of unequaled beauty with perfect balance of brilliance and fire. In layman's terms, the diamond is cut to make it the most beautiful diamond so it retains its intrinsic value.
Color In the near colorless category H color grade is the second best. Most H color diamonds have a very light yellow or gray tint that may be more noticeable when the diamond is placed on a white surface. Diamonds with H color grade appear white and are great values because they are more plentiful and as a result less expensive.
Clarity Diamonds of SI2 clarity are grade two slightly included. Depending on the location, SI2 inclusions in these diamonds may be perceptible to the naked eye. Good color SI2 clarity diamonds are an attractive choice when working within a fixed budget without sacrificing beauty or value. These diamonds balance good clarity with exceptional price.
