I recently became engaged and my fiancé proposed to me with a gorgeous diamond solitaire engagment ring. The jeweler from whom it was purchased strongly urges his clients not to wear their wedding band next to their engagement ring after marriage. He says that the two rings rubbing against each other causes damage to the band and setting of the engagement ring. He recommends instead wearing them on separate hands. I personally have never seen someone do this - does anyone out there have any opinions on this? I don't know how I feel about wearing the rings on different hands - yet I don't want to damage my beautiful ring or shorten its lifespan. Help!!!
