The wedding band is traditionally worn on the ring finger. This developed from the Roman “annulus pronubis” when the man gave a ring to the woman at the betrothal ceremony. According to tradition in some countries (derived from Roman belief), the wedding ring is worn on the left ring finger because the vein in the left ring finger, referred to as the “vena amoris“, was believed to be directly connected to the heart, a symbol of love.
Originally the wedding band was worn by wives only. Wedding rings became customary for both husbands and wives during the 20th century.
