On the diamond certificate, or diamond grading report, it is easy to read colour, clarity, carat weight and shape… But how do I tell if the diamond is well cut?

On the diamond certificate, or diamond grading report, you must look at the proportion grade, polish grade, and symmetry grade. These three grades together determine the overall make of a diamond, and are each respectively graded as either: Excellent, Very Good, Good, Medium or Poor. The characteristics section of a Diamond Grading Report will tell you if there are any extra facets, naturals or holes in the diamond.
