Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds of premium cut are almost as good as ideal. While nature determines the color and clarity of a stone, diamond cut is dependent solely upon the skill of the cutter. Premium cut diamonds may be close to the ideal cut proportions and look just identical. Most people cannot distinguish between the two. However, there is a slight difference in quality and reduction in price over ideal cut diamonds.
Color E color diamonds are virtually colorless. E color grade is very rare. The naked eye will not detect any presence of color. E color grade is indistinguishable from D without instrumentation.
Clarity VS1 diamonds have very small inclusions. Usually an experienced grader does not find any internal faults, but does not have great difficulties to see the inclusions when he moves the diamond a little from side to side. Typical inclusions of this group are small, light clouds or small light cracks on the girdle.
