Thanks for the advice and congratulations so far - the latter might be a bit hasty though, I haven't even asked yet!
I'm young-ish (28) and both a bit of a traditionalist and a pragmatic - so while I see the benefits of making a day of picking the ring, the other part of me is screaming nooooooo. I'll need to resolve this internal conflict myself!
She's not much of a jewelry wearer. When I get the ring, I'm sure it will be worn infrequently (she works as an auditor in food and catering, so jewelry is a no-no). I expect like the rest of her stuff, it will be worn sparingly on occasions only.
Thanks again for all the insight. Anything more is appreciated, I'll be checking this thread whenever she isn't hovering...
