I embrace the idea, however I am very non traditional. I think that times have changed. I see a lot of diamond solitaries now on women who I personally know are not engaged, and I think it looks great. SO just got me a diamond promise ring. If we suddenly broke up, of course I would still wear it because it's a really pretty ring. (Better to wear things than just have them sit there anyways.) I think bigger, solitaire style diamonds are often misinterpreted as engagement rings and that simply isn't the case. We are in an age now where independent women buy fancy jewelry for themselves and wear it with pride--rings included--so I don't see anything wrong with it. I think the same of myself if many years from now, I never get engaged. Am I never gonna wear my dream ring if I never get married? Absolutely not. Life is too short. Wear what you like.
