Ok, I am in the middle of CoS again, and on page 52 (American 
version) there is a mention of a magnificent necklace of opals 
that has a card by it that says it's cursed and has claimed teh 
lives of 19 Muggle owners to date.  (This was in Borgin and 
Burkes).  Then I hurried up and went to check GoF and sure 
enough, in the Beauxbatons and Durmstrang chapter, Madame 
Maxime turns up wearing a magnificent necklace of opals.  No 
idea what this means, if anything at all, but I thought it was worth 
mentioning just to see if anyone has any ideas.
