The given diagram illustrates the process of diamonds transporting from mines to retailers.
Overall, diamonds pass through about ten steps before they are send to retailers, the number verifying based on their sortage.
In the first stage, after rough diamonds are mined they are sorted based on their grade. Compared to lower grade, high grade diamonds go through more complex processes; for they are used in cosmetics. Following that, diamonds are analysed by computers for the best possible cut, either by machinery or hand. As for the final steps, they are polished, given a rating and shipped to retailers.
As for the diamonds who don’t make it to high grade, they are placed in industrial use. Unlike the high grade diamonds, their cutting process comes way earlier, just before they are tested for hardness. Having been tested, they’re simply priced and sent to retailers, in the same way as high value diamonds.
Consequently, the separation process of rough diamonds consists of many steps, which differs for both values of diamond.
