The 2nd one is a H&A stone, so to be safe i'll go with ACA.

I'd back up DF... AGS
There's slightly more weight in the first stone sure but the depth is greater...

you haven't supplied angles for the first stone, but judging on what you have posted, I'd go for the AGS

I have angles for the first stone :
36 crown
40.8 pavillion

I am leaning towards the 1 st one because of clarity and little bigger size and fact it's the same vendor as my ring setting.Is the stone really much lower quality?

Well, I ran the numbers through the HCA and the first stone came back as a 3.6 (buy only if price is right), so as a person who's owned ACAs in the past, I'd go with the second stone b/c it's going to be much more impressive in its performance. If you're interested in the first because of it being larger, then possibly shop around a bit more rather than purchase that one because, even if it's bigger in weight, it's not going to look as big due to it not having as good of light return as the ACA.

Also, with the first, you're spending more to get that higher clarity...you'd be better off looking for a stone of that size that is BETTER CUT and an SI like the ACA you're also considering.
