They are important factors in terms of determining the value of a diamond, but as the preceding discussion has shown, they do not tell the whole story about the diamond. Inevitably, evidence abounds of every technique known to improve the perceived quality and value of the sapphire; alteration of color, synthesis, composites, and misleading names. Techniques have been developed to treat natural sapphires to remove a certain type of flaw (needle inclusions) and to change the color; for example, to create a Ceylon sapphire that never came from Sri Lanka but whose color looks like that of a Ceylon.

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 D color diamonds are absolutely colorless. D is the highest color grade. Natural diamonds of this color grade are extremely rare and expensive.
Clarity VS1 clarity diamonds are very slightly included grade one. VS1 diamonds are less expensive than the VVS1 or VVS2 grades and present an excellent value. They have minor inclusions that are bigger and more noticeable than in higher clarity grades, but they are only visible at 10x magnification. To the naked eye, these diamonds will appear unblemished.
