The woman's wedding set, composed of the engagement ring and the wedding band, is a very important element signifying her commitment and devotion to her husband, as expressed in their nuptial vows. It is a constant reminder of this commitment, long after the wedding is over.
The way a woman wears her wedding set actually varies, depending on the culture and tradition of the bride and groom's native country. The most common and universally accepted way of wearing the wedding set is on the ring finger of the left hand. This is due to the belief that the left hand's ring finger has a vein directly connected to the heart.
How to Wear It
Traditionally, the bride does not wear her engagement ring during the wedding, or wears it on her right hand, to give way for the wedding ring. After the exchange of rings, she transfers the engagement ring to her left hand. The wedding band is worn first so it is closer to the heart, then the engagement ring, making it a kind of protection for the former.
Ideally, the wedding and engagement rings should match, to create an impressive wedding set. Have them designed using the same metal and some kind of symmetry, for a more beautiful, unified appearance.
