Didn't she already gave back those jewels, the ones from people deemed as innocent?
So after checking previous chapters, the recipients supposedly aren't that innocent, as some come from corrupt nobles, but most are of unknown origins. That said, she didn't give them back, she just scattered them amongst the poor people, including the ring that FMC gave to our MC, probably (unless we find out next chapter that she still has that one, which she better hope she does, or she likely won't be walking out of here).
