There is no official guideline or etiquette that covers whether or not a widow should wear a wedding ring after the death of her spouse. Rather, the choice to wear a wedding ring after a spouse's passing is personal and should be left to the individual.
Professionals recommend a widow only remove her wedding ring once she feels that the time is right. Rushing the process can cause additional grief during an already emotional time. Professionals also recommend that a widow's friends and family members do not judge her for either removing or refusing to remove her wedding band.
For some widows, the decision to stop wearing a wedding ring can be made shortly after a spouse's death. For others, however, a longer grieving process may be necessary.
