Today, few fine diamonds over one carat are sold without a diamond grading report, or certificate, as they are also called, from a respected laboratory. The finest jewelry often uses platinum mixed with 10% iridium or ruthenium for added strength. This selection usually depends on personal preference, skin tone, and the color of other jewelry you may own.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality The ideal cut diamond is a very precise mathematical equation, where diamond proportions and angles are cut to optimize the diamond's superlative optical properties, in particular it's high refractive index and color dispersion, to create a diamond of unequaled beauty with perfect balance of brilliance and fire. In layman's terms, the diamond is cut to make it the most beautiful diamond so it retains its intrinsic value.
Color Diamonds of E color are virtually colorless. Only less than 0.7% of natural diamonds have this color. Diamonds of this color grade will appear colorless even when observed face down against a flat white background.
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.
