Because of their hardness, diamonds are also used to cut and wear away other substances and are used for industrial purposes in drills, saws and engraving tools. They can make lovely jewelry and, depending upon other quality factors and overall personality, color. This principle applies especially when you are looking at old jewelry for possible purchase.
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 Diamonds of F color are very close to colorless. Very small percentage of natural diamonds fall into this category. Even a trained professional will not be able to detect presence of color without instrumentation.
Clarity Inclusions and external blemishes in diamonds of SI1 clarity may be easy to spot under 10X power magnification. Location of the inclusions greatly affect their visibility to the naked eye. SI1 diamonds of good color produce as good of a sparkle as the more expansive VS graded stones of lower color. Excellent bargains may be fond in this category.
