For me it's a tie between Nagini and the diadem of Ravenclaw.
I’m a bit biased so Diadem
The diary because it, along with the locket, is so fascinating psychologically.
I'm very into aesthetics so I chose the diadem. It's just so beautiful
I love Nagini. Especially when Neville turned her to ash. But I love the way that Tom can talk through the diary
What do you think?
