Since the diamond merchant doesn't actually see the credit/debit card in these situations then it's harder to be sure that the person supplying the card number details is actually the card holder and not someone who just happens to know the credit/debit card number. The real reason they do not display the weight is because the easiest way to make gold jewelry cheaper is to use less gold and make it lighter. But the problem with using less gold is that the jewelry will usually be weaker and more likely to bend.
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 H color grade diamonds are second best in a colorless category. Most H color diamonds have a very light yellow tint that may be more noticeable when the diamond is placed on a white surface. Such diamonds look beautiful in platinum and white gold and offer outstanding value.
Clarity VVS1 diamonds have extremely small inclusions, completely invisible to the naked eye. Typically under strong magnification such inclusions appear as minute white dots and are difficult to spot. VVS1 category diamonds are the perfect choice for people looking for perfection and purity.
