The definition of each net level at the clarity level, and divided the clarity into 11 levels, which is more detailed than the European level. Or defects, as the internal content, thus the role of these characteristics at the evaluation of the clarity level. Especially in the judgment of the FL clarity level, external characteristics play a very important role. In terms of cutting level, based on the ideal round diamonds of the United States, measure the proportion of standard round diamond -type cutting, and propose the concept and method of system evaluation.
