Cushion Cut Diamond for BGD Novela

I'm pretty confident that I've narrowed down my choice for the ER setting to the Brian Gavin Diamond Novela or the platinum setting by GOG (#1003). I am trying to come up with a ring that is as close as possible to the Tiffany Novo and after careful extensive searching, found that I like the Novela setting the best even though it is a little different from the Novo. Honestly, the Good Old Gold setting might be comparable or may be even a closer match to the Novo, but their photos don't really provide a good view and I haven't seen many PS postings showing rings with that setting.

I am looking for a squarish cushion cut diamond but also want to keep the cost down which may rule out the Square H&A (Quadex) so it does not have to look perfectly square.

Are you able to tell what type of cushion cut is displayed in the link below? It is described as 'Signature Cushion Brilliant', but is that like the Quadex or like a different type of Cushion cut?

From what I have seen, it appears that virtually any reasonable cushion I place in this setting would look great, but just wanted to get some feedback. Since I am trying to come up with something close to the Novo, I guess I am looking for an alternative to the Square H&A that would come out at a better price point, but still look good. Thanks.
