Hello,
First of all congratulations on buying a big diamond that is certified by the GIA.
Well, a GIA certified diamond has its own identity globally and it assured you of a legit and scientific method of appraisal/testing, in fact, GIA is the mother institute of all diamond grading and appraisal services worldwide.
Apart from your diamond, it is a 2.00carat cushion cut diamond with a bit THICK to the SLIGHTLY THICK girdle. I assumed that the diamond girdle is a bit thick to get a perfect 2.00 weight and it must be the reason behind the girdle thickness. However, the diamond has negligible flaws and seems very clean from its center. Even, the diamond polish and symmetry described 'excellent' in the certificate. In all combinations, your diamond is a perfect masterpiece.
All the best!
