I'm probably odd, but I personally wouldn't be marrying anyone who "caved" to social pressures about a non-functional fashion accessory barely noticeable from anything other than up close. Thankfully, I already found someone like that.
I prefer this strength in women - as it is not an isolated feature of personality. Life is too short to spend it with someone that shallow, unless that is exactly what you want/need.
And yes, if it's not clear, women requesting diamond rings as statement of true love (that's just not true and won't make the relationship any better), or blabbing about 3-salary-worth of diamonds... meh, I say you can do better.
