Yes, men can and do wear engagement rings. Though traditionally worn by women, the decision to wear an engagement ring is entirely up to the individual. Regardless of gender, an engagement ring symbolises the love and commitment one has for another.

An engagement ring typically features a prominent stone and is presented during a marriage proposal, while a wedding ring has a simpler design and is exchanged during a wedding ceremony. Traditionally, an engagement ring is worn by one partner as a symbol of the promise to marry, while wedding rings are worn by both spouses as a sign of their union.
