Sorry about Trump, BTW.
We're much happier with $20 disposable rings (both of us have lost one already); no fear of loss or damage and it gets the point across fine- hell, when I proposed to her I didn't even have a ring, we would have done it this way in the first place.
Interesting, I'm from Europe and I'd be curious to know at which point exactly did diamond rings replace gold wedding bands as the "official marriage signs" in the States. Wedding bands are still quite popular over here in Europe, hopefully they don't get replaced any time soon (for one thing, gold actually has some intrinsic value compared to diamonds).
They didn't. Wedding bands are still the "official marriage sign". Diamond engagement rings are extremely common, however, and it's very common for American women to continue wearing their engagement ring alongside their wedding band.
(As with my wife and my mother, it's definitely not unheard of for women to wear just the wedding band either).
I don't think this is a universal "in America" thing. Maybe in some parts of the country, but here in the northeast it seems like it's none of their business; I can't imagine asking someone to explain it, and I would think someone who did ask was being awfully nosy. FWIW my wife has a diamond ring which she almost never wears, and I can't remember anyone ever asking about it. My parents wear plain gold wedding bands only, and I've never heard anyone ask them about it either.
