Most diamonds really will look whiter especially under lights that give off a certain blue component. They can be resized about a size in some cases but it depends on the design of the ring. If you do need a resize at some stage you would be advised to take the ring back to the manufacturer for this special service.
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 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 Diamonds of VS1 clarity are very slightly included grade one. VS1 diamonds with tiny inclusions that are difficult to locate. Only a trained eye looking through a 10X loupe can pinpoint the inclusions in this category. The inclusions are nearly impossible to see with the naked eye. Excellent buy by all means.
