I recently has my original wedding band and ering made into one ring (my avatar--not a very good picture but you get the idea), and I wish i had seen this picture sooner!
I have been married 7 years and found I didn't wear my original set hardly at all after getting some beautiful anniversary bands, plus my tastes totally changed from yellow gold to platinum, so i did the redesign.... I love "X" rings and would have seriously considered something like this, esp. because my stone has a thin to med girdle and I worry about whacking it...
