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 K color diamonds have faint yellow color. Mounted in yellow gold, they look dazzling. Look for diamonds in this color range with medium to very strong fluorescence to minimize yellowish color effects. Choosing K color diamond allows to go for a bigger size and more extravagant look.
Clarity The stones of SI2 clarity have inclusions which are fairly easy to see under a loupe with 10X power magnification. 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.
