Married about 12 years (together 16). I bought my then future-wife a ring for $200. She didn't care it was small or that it was a tiny fraction of my salary - we both wore our rings for everyone else for a year or so... My personal do-over would be to have purchased an even cheaper ring (or none at all) so we could buy more useful things, and she would agree.

In any case, the spell doesn't work on everyone.
