Internal defects in diamonds are called inclusions. You have no idea whether the sales clerk in the jewelry shop next to the shoe store in the mall really knows what they are talking about or if they are just trying to make a large commission. Another advantage of buying fine jewelry online is convenience you need travel no further than your computer to choose your jewelry and make your purchase.
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 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.
