There is a difference in the identification of the purchase of loose diamonds and finished diamond rings.
The loose diamond custom diamond ring has been quietly popular among consumers. First, buy a loose diamond and then customize the diamond ring for yourself. It is cheaper in price and more personalized in style. However, many consumers of custom diamond rings are very strange. There is a certain difference between the certificate of buying a loose diamond and the finished diamond ring. Why is this?
This is because diamonds have some influence on the judgment of the diamond level after setting.
The most obvious effect is of course the color:
Only bare diamonds can correctly match the color, because the color grading of diamonds has many strict requirements. In the case of loose diamond grading, it must be the waist that faces the bottom of the diamond, and the diamond is set. It is upwards, so the fire of the diamond itself will largely conceal the body color of the diamond. Therefore, it is difficult to accurately judge the color grade of the diamond when the diamond is facing up. Moreover, after the diamond is inlaid, the color will be affected by the color of the surrounding metal. If the white metal is placed next to it, the color of the diamond will be white, and when the yellow metal is around, the color of the diamond will also be reflected. Yellowing will have a certain impact on the observation of the inspectors.
The second is clarity:
The clarity of the diamond is not accurate, because the cleanliness of the loose diamond is to check the crown, the pavilion, and the waist. The diamond is set in the crown. To observe the clarity of the diamond, some can check the waist, but due to the limitations of the style, it is almost impossible to check the clarity of the diamond from the pavilion. Anyone who has been involved in diamond grading knows that many of the inclusions in the diamond may not be visible from the crown, but if you look at it from the pavilion, it is very easy to see.
It is also very important that when the clarity of the inlaid diamonds is checked, some places that are blocked by the metal are not visible at all. That is to say, it is impossible for the inspectors to remove the inlaid diamonds. Full inspection. Therefore, there are many blind spots in the check of the purity of the mosaic diamond.
Sometimes there is a difference between the bare diamond certificate and the finished product certificate, not only because of external factors, but also more likely to be affected by the testing standards. For example, we buy a 50-point foreign certificate loose diamond, and after the customization is completed, we have issued a certificate of NGTC. The two will also differ due to different standards.
