4.3. FINISH

4.3.1. DETERMINATION OF FINISH

When determining the finish grade, the symmetry-characteristics of the shape and the distribution of facets are taken into account, as well as extra facets and naturals.

The four main symmetry-deviations are:

  • variation on the diameter (for brilliant-shapes)
  • variation on the crown height
  • deviation of the table from the central position of the diamond
  • deviation of the culet from the central position of the diamond

4.3.2. FINISH GRADES

The Finish grades are:
very good - good - medium - poor
