I've recently had the experience of designing an engagement ring for my soon-to-be fiancée and I've been debating with myself about traditional styled vs modern/personalized rings. As I understand it, and as the article suggests, rings have been meant to be timeless; something that is passed down through generations. Will non-traditional rings be a regret 20, 30, 40 years down the line?
IMO, I'd just go with what you want to wear. TBH, you will be lucky if you don't lose the ring sometime between now and when you pass it down. Also, if you do pass it down, it is just as likely to sit in a drawer than be worn on a descendant's hand. Get them for yourselves, whatever that may be.
I went simple with my wife's setting but went all out with the diamond. I figured we could change the setting and the band as we could afford to. We have been married for 7 years now and on our 5th anniversary I told her I was getting it cleaned and surprised her with a new setting. -It's bad ass. It's not "flashy" but elegant. -Timeless.
