Question regarding stone, primarly large table %... Your thoughts?

[JMosher]

Hello...
This is my first post so please reply in kind! I found a stone I like but I wanted to get some other opinions. Quoted from GIA Dossier its a 0.73 ct. Round Brilliant. Measurements are as followed: 5.71 - 5.76 x 3.55 mm. G, IF, Excellent Cut.
Depth: 61.9% TABLE: 60% Crown Angle: 35* Crown Height: 14.5% Pavillion Angle: 41*
Pavillion Depth: 43.5% Star Length: 55% Lower Half: 80% Girdle: STK Faceted Culet: None
Polish: Excellent Symmetry: Excellent Flourescence: None Comment: Minor details of polish are present.

Now to me that table % seems high but given the other factors what do yall think? I just thought in order to be considered as GIA excellent cut, the table had to fall within the 53-57.5% range? And lastly whats up with the comment "details of polish"? Is that ok? Also, when you have an excellent cut with excellent polish and excellent symmetry dont you get the hearts and arrows effect? Im new @ reviewing stones so any info, comments, opinions, or thoughts would be greatly appreciated!

I look foward to your replys and thanks for your time!

angles are a little off for a 60%

The EX grade can go up to 62%

"Details of polish" is nothing to worry about, since this stone has EX polish.

Hearts and arrows don''t happen because you have EX EX.

Hi Jared!

Just because a well cut diamond might show an arrow pattern does not mean it is a true example of the cutting style, see this thread for an explanation of the hearts and arrows cutting style.

Well said, Lorelei. Precision-cutting to create H&A indeed does NOT have a direct relation with lab-graded symmetry, and definitely NOT with polish grades though I can well understand how confusing this must seem for newcomers.
Paul-Antwerp has just informed me that later this week, the HRD will be presenting their new system of grading H&A. I am looking forward to his report on that.
