Round Diamond Proportions - Slightly thick and high table, does it matter?

by uphone » Mar 1, 2019

This stone falls within all recommended guidelines (except for a higher table and slightly thick girdle), including complimentary pavilion guidelines, triple ex rating. It also scores a 1.4 on the HCA with excellent in all categories and very good in spread. Is there anything specific from the numbers or videos that hints that this will not perform relatively well besides optical symmetry?

End poorly? I've said I will get it independently examined before payment. Let me know if there are any other steps I should take to make sure there are no issues.

Based on this AGS chart for the 59% table, 35 crown angle and 40.6 pavilion angle, it sits as AGS Ideal.

Is there another chart or resource I should be looking at?

Thanks again for everyones input. Just got back from a vacation and am looking to finalize my ring within the next week before April 1st. My wholesaler got back to me, and I think there was a confusion in the messaging with all the different stones. It was actually $11,800 for the stone instead of the $10,900 I originally stated. I also found another stone I'm interested in from an online retailer. These are the final prices and specs of each stones. Which stone is better for the money? Not sure which one to go with.

I saw the 1.64 H VS1 in-person, under the loupe I was able to see some of the black marks on the table, but looked eye-clean without it. I haven't seen the 1.65 H VS2 in-person, but provided a video. Retailer said it might look cloudy because it needs a cleaning, but it comes with 30 day return policy since I haven't seen it in-person.
