Western tradition requires that the engagement rings are to be worn by a lady on her left hand ring finger to indicate that she is engaged to be married. However, in present day usage, the engagement ring is given to a woman by a man at the time of proposing marriage and acceptance of which would lead to her wearing the engagement ring, which is presented as a betrothal gift and signifies the formal acceptance to marry in the future.
Other traditions have also followed similar conventions dating back to the classical period when the engagement ring was worn on the fourth finger of the left hand and was sometimes referred to as vena amoris, the vein of love.
Presently, in the United States, it is becoming more common, even though it is still quite rare, for a woman to present her man with an engagement ring, when she is getting engaged. Whereas in Europe, more particularly Sweden, Denmark, Finland and Germany it is common for both partners to wear rings, though in these lands the engagement ring may also double for a wedding ring.
