Foreshadowing to Half Blood Prince

Okay, after watching the Half-Blood Prince, I decided to reread the Harry Potter series. I caught something very interesting in Chamber of Secrets.

When Harry accidentally ends up in Borgin and Burkes, Rowling describes Malfoy looking at a necklace....

The necklace was cursed, and Draco was looking at it. Does anyone else think this was the necklace used to curse Katie Bell?

That never even crossed my mind! Kinda cool...
I think that could be. I mean, it's probable. JKR would involve something like that, now that you mention it.

If you'd read the book and/or watched the movie, you would know what I'm talking about. Katie Bell was cursed with a necklace in Half-Blood Prince...

For your information I saw the moive.I can't think what to write.

Oh. Well, could you possibly join in on the movie discussion thread? I'd love to hear your thoughts.

Theres only a few places you can get cursed things but, don't you think it would have been sold by now before the 6 movie.Why would Dumbledore give the cursed necklace to Katie Bell to deliver to him.
