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.

In older times, the wedding rings were not only a sign of love, but were also linked to the bestowal of 'earnest money'. According to the prayer book of Edward VI: after the words 'with this ring I thee wed' follow the words 'This gold and silver I give thee', at which point the groom was supposed to hand a leather purse filled with gold and silver coins to the bride.
