The answer to this question depends on your relationship and situation. If you are in a long-term committed relationship with your fiance or spouse, then it is likely that you will continue to wear your alexandrite engagement ring even after getting married. If you are married but only have a civil partnership, then typically the ceremony will not confer any legal rights so you may choose to remove your ring after the fact. If you are just dating or engaged, it may be more appropriate to keep your ring on until the wedding day.
