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 Diamonds of G color are nearly colorless. G color diamonds may have a slight yellowish tint when viewed against white flat background. When set in platinum or white gold jewelry the presence of color will not be noticeable which makes diamonds in this color grade very popular.
Clarity SI2 clarity diamonds are slightly included grade two. SI2 inclusions in diamonds are easily visible under 10x magnification. These inclusions may or may not be discernable to the naked eye depending on their location on the diamond, but these diamonds still presents an excellent value.
