that's horrible, I'm sorry it happened to you. Like others have said, I would still try the pawn shops and even online.

I once got broken into and they took my grandfather's wedding band. He died before I was born, and it was extremely sentimental. It probably wasn't worth much to whoever stole it and tried to hawk it, but it took me a very long time to get over it (can you actually get over something like that?)

Hugs to you, and don't give up, keep looking!
