I wear my second wedding band with a cubic zirconia engagement ring that kind of matches it. When I married my beautiful wife I knew that our matched wedding set wouldn't be safe in my mostly outdoor work in the field. I was given my great-grandfather's wedding ring as a second. It is gold, narrow, but not entirely plain. It is only about 3 mm wide so it is typical of many lady's bands. This combination works for me when enfemme. I just don't feel right without one of my wedding rings.
