Below 8 points, show the gem certificate, and there is no specific evaluation on color clarity and cutting. Colors are often identified as colorless, feathery and other cleanliness, and cutting is empty. . It is reasonable that diamonds are too small to accurately distinguish color from clarity.

8~20 points (excluding 20 points), show the mosaic classification certificate and classify the color clarity (expressed in letters, such as color I-J color, clarity VS, etc. If it is in Chinese, such as white, it is not standard). . Yes, the job is empty.

20 ~30 points (including 20 points), show the mosaic classification certificate, and evaluate the color clarity and cutting work in detail. . Both the width ratio of the platform and the depth ratio of the pavilion are available (two data of cutting work).

Above 30 points are the most standard in the world, so I won't go into details here.
