My wedding band is yellow gold with three small diamonds, and a tiny bit of engraving on each side, that was custom made in Newport. Even after 30+ years, I still get compliments on it.
I never had an engagement ring, but on my 40th birthday/15th anniversary, DH gave me an emerald cut diamond flanked with 2 trillium cut diamonds (also custom made). He also had his mother's star sapphire reset with diamonds for our 10th anniversary, so I'm all set as far as rings go.
DH is working on his third plain gold band, which he wears all the time now.
