One of the unusual quirks about my dad was that he never wore a ring. I don't know about customs in other countries, but in the USA, it is customary for married people to wear a wedding ring the the fourth finger of the left hand to let everyone know they are taken. Although my dad was a loving, faithful husband for over 50 years of marriage, he refused to wear a ring because he worked so much with his hands and felt he would either lose it, damage it, or it would be uncomfortable for him. My mom wore one, but allowed my Harry to do his own thing and didn't make a big fuss about it. He was definitely his own person and really didn't much care what others thought and certainly wasn't going to let society dictate what he would and would not wear.
Although I'm not big on jewelry either, I do wear my wedding ring. I just got one ring and used it as an engagement ring and wedding ring. My husband wears one too and I'm glad he does!
