Tarot gifts?

My friend's birthday is coming up and im sure they're really like a tarot themed gift, but i'm a bit clueless to be honest!

Because they've already got a deck, I was planning to get them a necklace of one of the major arcana, but I was wondering what i should be mindful of in terms of the significance of which major arcana 🙂 so i was wondering 1) if the meaning of the arcana would be important here, should i make sure to get a specific one rather than just going off which looks the best, and 2) do people tend to have "favourite" arcana, and should i try and find out what theirs is?

Thanks 😀 (and sorry if the questions are a bit foolish, like i say i'm very clueless!!)
