Place the diamond grading report somewhere safe in case you have to have your jewel taken into the shop or in case it's stolen. You could get her a less expensive ring with a lower profile (not so raised off the finger and not so flashy) and she will be very pleased. Just take notice on how much and what type jewelry she wears and what her opinions are on the subject and use your best judgement.
Explanation of Cut, Color and Clarity of This Diamond
Cut Quality Diamonds of premium cut are almost as good as ideal. While nature determines the color and clarity of a stone, diamond cut is dependent solely upon the skill of the cutter. Premium cut diamonds may be close to the ideal cut proportions and look just identical. Most people cannot distinguish between the two. However, there is a slight difference in quality and reduction in price over ideal 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 VVS2 diamonds have very very small inclusions which, when viewed under 10X magnification by an expert, are difficult to be seen. The inclusions should be light colored. The features of the VVS2 clarity grade are exceptionally difficult to discern. Diamonds of this clarity appear to be perfect to an unaided eye.
