Many stores will create their own diamond certificate in some cases this would be alright if you are dealing with a store that has a GIA certified diamond grader who would be grading the diamond and doing a certificate for your stone. You can get a pair of earrings with your name on it. Or a credit card size earring with a freaky message on it.
Diamond Certificate
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 Diamonds of D color are absolutely colorless. It is the top most color grade and only 0.3% of all diamonds that make it out of the earth being D color.
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.
