Advice on 1.17 ct with GCAL Report

[ilovedessert]

I've been reading through the forums and doing some research in order to make the best choice for an engagement ring. I found a pre-owned ring with 3 round cut diamonds (center = 1.17ct, side stones = 0.33 ct each). I've obtained the GCAL report:

The seller is asking for $7,500 for the ring. I know the clarity and inclusions (I, SI1), as well as the polish and symmetry, aren't great, but the other specs aren't raising red flags based on my extremely limited understanding. What are your thoughts? Is this a good value?

Any insight would be greatly appreciated!

GCAL brilliance analysis is crap, this stone should not get more than VG/G if they follow the same scale they use for a BN Signature Ideal stone. The girdle looks too thin if they are describing the max thickness, much easier to chip if that is the case.

I don't think it's a good value. This 1.08 ct AGS Ideal I SI1 is marginally smaller, but still leaves ~$2,000 for the side stones and setting.
