So my diamond comes in at a 1.7 (excellent) on the HCA calculator and excellent on the GIA site calculator. But the GIA statement grade is Very Good. I''m told by Garry it''s due to the girdle which is slightly thick to thick (which defaults it out of Excellent and into Very Good). But all things considered, I''m curious what I''m sacrificing. Anything? My initial guess would be spread (as some of the weight is in the girdle), but the spread comes up excellent on HCA (probably due to the 61% table). My next guess would be light performance, but I''ve read on numerous sites the slightly out of ideal range girdle has absolutely no meaningful effect on light performance.
So the cut adds up to Excellent light performance and Excellent spread. Assuming I''m fond of a slightly larger table (which GIA now recognizes as subjective) for all intents and purposes, shouldn''t this be considered an Excellent graded cut as all the positives seem to be here? Should I look at it as a steal for getting a Very Good grade price? I''m not looking for validation here. I''m just trying to better understand grading/pricing. Obviously if the girdle was medium throughout you''d rank even higher on the "excellent" side.
So....is it as simple as this: If you like a slightly bigger table %, you can afford a little weight to go to the girdle which defaults it to a lower grade which saves you money. Am I on to something? Am I way off?
