1. An engagement ring is first worn in public on the day the engagement is announced; in Western tradition, it is worn on the ring finger of the left hand, though in some countries, it is worn on the right hand. During the wedding ceremony, it is removed and quickly replaced by the wedding ring.
2. Engagement rings are typically set with gemstones or other ornaments and feature a seamless band, symbolizing a love that is pure and flawless-leaving no "crack" for outsiders to exploit. In contrast, wedding rings must be plain bands without any gemstone settings.
3. Engagement rings should not bear any inscriptions, whereas wedding rings may be engraved with the couple's surnames, initials, or the date. Like wedding rings, engagement rings must be made of high-purity platinum, gold, or silver; the man places the ring on the woman's left ring finger in public and kisses her hand.
4. An engagement ring is not a requirement for an engagement to be valid. While some people believe engagement rings are just as essential as wedding rings, this is not the case; many wives never have an engagement ring.
