Have you tried contacting the jeweler to see if they can make another one? I bet if you tell them what happened they would be happy to make a new one for your wife.

I know exactly how you feel!

There were actually three "whoops just kidding" moments with Land dying.

You are right!

Finished it last night and wow! I was very happy with it overall. The only thing that bugged me was Lan seams to die killing Damodred, but then he's not dead. Mat seams to die (twice) with Fain, but then he's not dead. I'm happy they are alive, but it was like...what? I was very happy with the Olver/Noal scene, that really got me and it was the one time I cried. 

Right now I am reading Lord of Chaos, book six of WoT and I love it. My plan is to keep reading through the series until finished.
