Necklace.
Draco Malfoy, hoping that the necklace would get to Dumbledore.
yes, but she didn't break the heart in half. it's one of those necklaces that comes in two parts, she has one half and Michael has the other.
Katie Bell was the person who touched the cursed necklace.
Yes she did when she took back the necklace.
Yes they are water proof!! :) Idiot... they aren't waterproof. You can go in water with one but i suggest you don't. They will sag stop working as well if they still work at all and they might break in half.
Harry never gave Ron a necklace; however Lavender Brown gave Ron a necklace in the sixth film, "Harry Potter and the Half-Blood Prince
you can find it at New York at the Lamaze City
Half of a heart shaped necklace that changes color, she kept the other half.
The atoms will break into half :)
Then you didnt break it in half
Well, break up with him; or take a break. He shouldn't act that way with you. Then, if it was special, go and get the necklace fixed. You need to show your boyfriend that you do not like to be treated that way, and that until he calms down his act you need some time off.
