Ever wondered why wedding rings are worn on the fourth finger? There is something almost magical about the moment a wedding ring slips onto the fourth finger of the left hand. According to historical accounts, wedding rings were not always worn on the fourth finger of the left hand. Simple rings evolved into bands made from precious metals and, eventually, elaborate engagement and wedding rings featuring diamonds and other gemstones. And from an anatomical perspective, there is no medical reason that requires a wedding ring to be worn on one particular finger.
