If you are looking to potentially use gems to expose the things in the gacha, you should wait until the girl is not doing an activity, go in to the gacha and if there is a momento to be picked among the boxes, then she will say something. Depending on the girl, but it's a pretty obvious clue that there is something for them there that'd be a momento. Or at least that's what I've discovered.
