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 D color diamonds are absolutely colorless. D is the highest color grade. Natural diamonds of this color grade are extremely rare and expensive.
Clarity Diamonds of VS1 clarity are very slightly included grade one. VS1 diamonds with tiny inclusions that are difficult to locate. Only a trained eye looking through a 10X loupe can pinpoint the inclusions in this category. The inclusions are nearly impossible to see with the naked eye. Excellent buy by all means.
