Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds cut to ideal proportions are made to reflect the most amount of light. High percentage of diamond weight is lost in the process of shaping and polishing the diamond. Such diamonds are perceived as most brilliant and fiery, thus making this the most desirable cut. Because in making ideally cut diamonds more diamond material is sacrificed for the sake of appearance, they are usually more expansive.
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.
