My wedding ring is nice - it has a .5 carat stone flanked by my DH's birthstone and a few more small diamonds. For my 10th anniversary I designed my own 3 carat diamond and platinum ring. I change out rings when the mood suits me. I don't wear a diamond ring on each hand, just one.
If you own a gorgeous ring... wear it! Make sure it is properly insured, get it reappraised every 2 years and wear it safely. Have the ring checked every year for loose prongs or loose fittings.
This thread is wonderful.... all sorts of engagement rings and wedding rings worn in the spirit of love! Congratulations to everyone and best wishes.
