The Wedding Ring on  is placed on the fourth finger on the left hand.  This tradition can be traced back to ancient Roman times.  Tradition has it that the Romans believed that the vein in the ring finger (the fourth finger) on the left hand ran directly to one's heart. Due to this belief, they called that vein the "vena amoris" or the “vein for love”.  Naturally, to solidify a union based on love, they would place the ring on that finger that housed the vein of love to signify the romance the newly married couple shares. The ring is held by the presenter until the ring vows are completed and then the ring is placed on the finger during the ceremony.
