Design Changing Help? Should I change it or not?

It’s a G VS2 excellent cut natural round 1.05 ct two tone solitaire. I am confused about the setting, does this look good? i am going to wear it occasionally and i gifted this to myself. is this secure enough to wear occasionally? I asked for tiffany mount with hidden halo, but it doesn’t look like tiffany mount to me. Also i wanted a plain band, they gave us knife edge which i am kindda liking it but kindda confused as well. any suggestions to make changes as they said if i don’t like it, they can change it for me. Also, I was wondering what would be the fair price for this type of solitaire? I paid $5670, is it overpriced?? any suggestions to make? or it just looks fine and it’s gorgeous?
