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 An E color diamond is extremely rare and slightly less expensive than a D but is so similar that most people won’t be able to tell the difference. You pay a serious premium for an E color diamond. Diamonds of this color grade will appear colorless even when observed face down.
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.
