What wedding ring goes with a halo engagement ring?

The cleanest way to settle the band shape is to slide a sample plain band against the engagement ring at the jeweller. A high-set or cathedral halo lets a straight 2mm band sit flush, and the small gap between the two rings reads as a deliberate line rather than a problem. A low-set halo pushes the band away from the finger so a straight band sits at an angle, and the gap becomes obvious from above. Most jewellers carry sample bands for this fitting and will quote the contoured option once you can see the misalignment in person. Settling the geometry before ordering is much cheaper than reshaping a band after the wedding.

A contoured band is curved to trace the bottom edge of the halo, so the two rings sit together without a gap. A notched band cuts out a small section to clear the halo, which lets the wedding band sit flat against the finger and the engagement ring sit on top. Contoured suits low-set halos with a curved outer edge, like round, oval and cushion. Notched suits halos with a flat or geometric outer edge, like emerald or asscher. Both options add modest cost over a plain band, since the shape has to be matched to the specific engagement ring rather than pulled from stock.
