An engagement ring symbolizes the promise of marriage. Traditionally, this ring is one that is given to the woman in order to signify that she is no longer available to suitors. However, some cultures encourage both partners to wear matching rings.
Usually, the woman’s ring is presented as a gift by a man to his future wife as he proposes marriage. It represents a recognized arrangement for marriage in the future. Some couples choose to exchange promise rings, which usually incorporate smaller diamonds, prior to buying a formal engagement ring. The tradition of wearing the engagement ring on the left hand index finger comes from the belief that the particular finger has a vein that connects directly to one’s heart.
