I did the spacer for a while but it collected dirt and I was started to shrink out of it. I bought a cheap but nice costume jewelry ring off Amazon and I wear my wedding ring on a necklace. As soon as I hit my goal, I'll get it resized.
EDIT: Link to ring I bought. Looks great and hasn't turned my finger green! https://www.amazon.com/dp/B0191UAI4C/ref=cm_sw_r_cp_api_HsT2xbH346ZBZ
