H&A will need to see the actual images thru a H&A viewer, average numbers means nothing for optical symm.

What is the carat weight of the AGS stone? What are the star and lower half size for both stone? From the numbers, unlikely #2 will be a H&A by traditional definition.

I'm by no means a gemologist, but as a diamond lover who is VERY color sensitive - I would vote for G !!
Both seem like excellent cuts, AND for $400 bucks less, get the whiter color. (IMHO) :wavey:

Re: Experts! G or H for a Round Diamond (based on these spec

I would definitely prefer a GIA G over an AGS H, but I don't like that very low crown angle on the G. There are thousands of 1 ct. stones out there, so I wouldn't limit my search to these 2. I'd try to find a crown angle of 34-35 and table 54-58.
