Traditionally, an engagement ring is a platinum or solid gold band that features a solitaire diamond at its center. Many variations of this style exist, including three stone settings with a prominent solitaire diamond surrounded by side stones.
In the past, only one person in the couple — the individual proposed to — wears an engagement ring. This has changed in recent years as couples have decided to exchange pairs of engagement rings, or purchase another piece of fine jewelry alongside an engagement ring to signify their commitment.
A wedding ring is usually a platinum or solid gold band that lays flat against the finger, with no prominent stone at its head. It can be embellished with diamonds, but these are usually secured inside the ring’s setting, instead of being displayed on top with prongs.
An engagement ring is exchanged at the time of the proposal. Wedding rings are generally saved for the wedding ceremony itself.
