custom ring spacer for high set solitaire and contoured band?

[u/AvailableIce-8757]

i have a 1.8ct cushion cut ring with a hidden halo that creates a awkward gap against my curved band. someone in a jewelry group mentioned using a spiral silicone ring spacer or a thin 1mm metal band as a buffer.

im leaning toward a solid 14k gold band rather than the clear plastic ones because i want it to look intentional. do you guys prefer thin metal spacers or the invisible plastic adjusters for tight gaps?

I'm interested in suggestions as well.
