If mom doesn't have a fixed income every month and her financial conditions are average, then you can give her a red envelope at this time. People are alive, at least when they have enough to eat and wear, and when they have no worries in their daily lives, can they consider other things? So in this case, it is not recommended to send a silver bracelet.
In addition to red envelopes or silver bracelets, you can also give your mother a sweeper or washing machine. Because housework is very hard, both of these gifts can help her share some housework more or less and reduce her burden.
