Diamond drilling and finished bare the differences of the ce

Buy now often have friends with an international certificate or certificate of naked domestic drilling, after which mosaic processing, such a ring down the cost accounting often than to the mall to buy diamond jewelry product cheaper. But for ordinary consumers, make the finished diamond jewelry certificate of shouting to do, the present results and certificates before the naked drill often have some differences, often so that we feel very confused, why the difference? clearly are with a diamond, then the following came to know the crux of which it!
This is because the diamond after the diamond-level mosaic would be a number of factors determine the impact.
First, color: Only the bare drill to the right than the color, because color grading diamonds, there are many strict requirements, in the bare diamond grading must be down to the table than diamonds, the most noticeable color waist edges Department, and good diamond inlay, table top is up, so that the fire of the diamond itself will largely cover up the color of the diamond's body color, therefore, the diamond table up in the circumstances, is difficult to accurately determine the color grade diamonds. And diamond mosaic is completed, the color will be overlaid with metallic color effects, if next to the metal with the white, diamond white color will be obvious, but surrounded by a yellow metal, the color will be against the background of Diamond yellowing of the testing of such personnel will observe a certain extent.

Second, the net degree: gold diamond clarity judgments are not accurate, because the bare diamond clarity grade is to do the crown, pavilion, check all aspects of the waist, while the inlaid diamonds, clarity in doing sub- level, only to observe the diamond from the crown of purity, there can check the waist, but because of restrictions on style, almost impossible to check the diamond from the pavilion net degree. Engaged in diamond sorting of people know that diamond in the number of inclusions, probably not observed from the crown, but if looking from the pavilion, it is easy to see. There is very critical that made gold diamond clarity when checking some of the metal block is that there is not see, that is, the inspectors can not remove the mosaic to better diamonds, finished completely All of the checks. Therefore, the net degree of diamonds inlaid check that there is a lot of blind spots.
It is not all that to their finished mosaic will differ from the bare diamond certificate does, in fact, not all, but when in the choice of style must be more attention, as we choose a simple style, this time in the test will not the emergence of many unnecessary blind spots, then the certificate is a great result there would be no deviation.
