Castellani became the first 19th-century jeweler to create works closely modeled after classical Italian and Greek prototypes, thus creating a new fashion trend.
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 F color diamonds are close to colorless. F color grade is rare and only surpassed by colors D and E. The naked eye will not detect any presence of color. For perfectionists, look for diamonds with low fluorescence.
Clarity Diamonds of SI1 clarity are slightly included grade one. Inclusions in SI1 diamonds are easily identified through a strong loupe. Finding flaws in this category with the naked eye is difficult. The diamonds in this category maintain their integrity, depending on the location of the inclusions.
