Extra information (01): engagement ring - Especially in Western cultures, an engagement ring is a ring indicating the that the person wearing it is engaged to be married. In the United Kingdom, and North America, engagement rings are traditionally worn only by women, and rings can feature gemstones. In other cultures men and women usually wear matching rings, which can be plain. In some cultures, engagement rings are also used as wedding rings.

Conventionally, the woman's 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. Rings can be bought by the man, the couple together, or by each partner for the other.

In North America and the United Kingdom, it is worn on the left hand ring finger, while in Poland and Ukraine, it is customary for the ring to be worn on the right hand. In Germany, the ring is worn on the left hand while engaged, but moved to the right hand when married. 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".

Betrothal rings were used during Roman times, but weren't generally revived in the Western world until the 13th century. The first well-documented use of a diamond ring to signify engagement was by the Archduke Maximilian of Austria in imperial court of Vienna in 1477, upon his betrothal to Mary of Burgundy.

In the 20th century, if he could afford it, the typical Western groom privately selected and purchased an engagement ring, which he then presented to his desired bride when he proposed marriage. More recently, couples frequently select an engagement ring together. (from Wikipedia)
