dfb - yes, I have a wedding band, just no engagement ring. H and I have plain gold bands with various symbols carved into them - we designed them ourselves (mostly H's idea). And of course, now I have a Hawaiian gold band on my other hnd from our 20th anniversary
I have a girlfriend whose engagement ring was her H's boy scout ring - they set a diamong into it and designed a nice band to fit with it.
Of course, after being on these boards, I now see the wisdom of getting a huge rock one could pawn when the bum takes off in MLC!
