You should not be charged extra for the diamond plot, and this should be done with a diamond certificate. The question is, how soon and how hard will higher gold prices hit the jewelry consumer. This will greatly depend on the type of jewelry store and how quickly they have systems in place to change their jewelry prices.
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 J color diamonds are more or less colorless. J color will be slightly detectable to the experienced eye. When cut to ideal proportions, the diamond will produce a warm intensity. This diamond is an excellent value for the budget conscious. J-color diamonds are the least expensive of the near-colorless grades.
Clarity VS2 Clarity diamonds are very slightly included grade two. VS2 diamonds have minor inclusions that are visible at 10x magnification. They are less expensive than the VS1 clarity grade because they exhibit slightly more inclusions. VS2 clarity diamonds make excellent choices for jewelry because the naked eye will not be able to detect any inclusions.
