While diamonds are one of the hardest materials on earth they can still be damaged. Thus, the value of gold in jewelry is worth only as much as the percentage of gold used. The first reason why jewelry is not an investment, therefore, is that you are buying karat gold, not pure gold, and gold is valuable simply because it is gold.

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 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 VVS2 clarity diamonds are very, very slightly included grade two. diamonds of VVS2 clarity have very small inclusions that are difficult to see even under 10x magnification. Though the inclusions are not quite as imperceptible as in a VVS1-clarity diamond, this diamond still makes an excellent choice for those looking for a balance of exquisite clarity and affordable price.
