Carol responds:

Harry asks Flitwick about the tiara, remember, and Flitwick says that
he doesn't know what happened to it. He thinks it's an academic
question, interesting to speculate about but not appropriate in a
moment of danger. The Ravenclaw students don't know, either. All they
know is that the statue of Rowena Ravenclaw is wearing the legendary
lost tiara. It seems likely that both Flitwick and Dumbledore asked
the Grey Lady about it (assuming that they know she's Helena
Ravenclaw) and that she told them nothing--especially after Tom Riddle
had charmed the secret out of her and she became even more ashamed of
her behavior. The Grey Lady makes it clear that she's been asked many
times, and only the information that the tiara can be used against
Voldemort persuades her to tell Harry the truth, not only about
stealing it in the first place and hiding it but about revealing the
secret to Tom Riddle. I think she'd feel the same way that Slughorn
feels about his memory of telling Tom about Horcruxes--she wouldn't
want anyone to know. Even though she's a ghost, she still has her
pride and still feels shame. It also seems that neither Flitwick nor
Dumbledore knows that the RoR sometimes functions as a hiding place
for forbidden objects. (I still don't understand how Riddlemort could
think he was the only person who had ever found a room full of
objects, but I do understand why neither Flitwick nor DD knew that the
tiara was in the RoR.)

Carol, conceding that DD should have known (and informed Harry) that
the powerful magical object most closely associated with Rowena
Ravenclaw was a tiara
