Wedding Diamond Engagement Rings

In Western tradition, an engagement ring is a ring worn by a woman indicating her engagement to be married. Conventionally, the ring is presented as a betrothal gift by a man to his prospective spouse while he proposes marriage or directly after she accepts his marriage proposal. It represents a formal agreement to future marriage.

In some countries, such as the United States and the United Kingdom, it is worn on the left hand ring finger, while in other countries, such as Poland and Ukraine, it is customary for the ring to be worn on the right hand. Similar traditions purportedly date to classical times, dating back from an early usage reportedly referring to the fourth finger of the left hand as containing the vena amoris or "vein of love".

In the United States and Canada today it is becoming more common, but still rare, that a woman will also buy her partner an engagement ring at the time of the engagement. These may be called male engagement rings or man-gagement rings, which is a portmanteau of "man" and "engagement ring".

Before agreeing to marry, a couple may choose to buy and wear pre-engagement rings, also called promise rings. After marrying, the couple may wear both engagement rings and wedding rings, or just their wedding rings, as they prefer.
