Alright, I've requested ASETs on those three. As far as personal taste goes, I'm liking the look of all of them, and with your advice I at least know I'm looking at good quality asschers!
As for the setting, I'm thinking of a simple solitaire, either classic or cathedral. I also really like the look of the baguette rings with asschers, so that's another option. My partner prefers rings without the small side diamonds (I think halo), but baguette rings look quite different from that so she might like those - it's still the less "safe" option. I also don't know her exact ring size (I only have a ballpark) and I reckon solitaire may be easier to resize, but I'm happy to be corrected on that one.
