Before being cut, it was a rather flat, blocky 110-carat rough diamond. Blue sapphire, another intensely colored gem, comes in numerous tones of blue; from light to very dark, some so dark that they look black in incandescent (warm) light. Most sapphires, however, look bluest in fluorescent light, or day light.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Ideal cut refers to the angles and proportions of a diamond that satisfy very precise mathematical formulas. The result is that the the ideal cut diamond internally reflects most light from one mirror-like facet to another and disperse and reflect it through the top of the stone. This results in a display of brilliance and fire, thereby placing ideal-cut diamonds higher on the quality pyramid than deep or shallow-cut diamonds.
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.
