Explanation of Cut, Color and Clarity of This Diamond

By all means such diamonds are considered well cut. In fact, many consumers cannot distinguish between the ideal cut diamond and the premium cut. Appearance of diamond is very subjective and cannot be fully evaluated just by their proportions along.
Color Slight presence of color may be detected in F color graded diamonds by an expert gemologist. The diamonds of this grade are considered colorless. Great choice for the purist. Look for a fluorescence rating of faint, inert, none, or negligible.
Clarity SI1 clarity diamonds are slightly included. SI1 diamonds have some inclusions visible under 10x magnification but not easily visible to the naked eye. A diamond with this grade of clarity is an excellent choice for someone on a limited budget.
