Aunt Adele's diamond choker

Unlike art, jewellery is often broken up to its valuable parts, the precious metal (gold, platinum, silver) and the jewels either because the original mounting was not important, or dislike by the new owner, or to avoid it being traced.

the necklace, stolen by the Nazis, was given to Herman Goering's wife as a gift. I don't remember what happened to the cello.

I did some research online and found some info on (what might be) the cello, including its possible location, but I have absolutely nothing on how it got to its current musician.

The cello was given to the Bloch-Bauer family by the Rothschild family. (http://www.telegraph.co.uk/news/obituaries/8311944/Maria-Altmann.html).

On Wikipedia, there is a list of all of Stradivari's instruments:

If you look at the 1710 cello, you see that it is called the "Gore Booth; Baron Rothschild" cello. There have been tons of Rothschilds, and they are all rich as f^%$, so it is totally possible that they owned multiple Stradivarius cellos and that this is not the cello that Mrs. Altmann's father, Gustav, owned. However, I do know this cello is currently being played by Rocco Filippini. How it got to him, I have no clue.

I did look further into this, and it appears that this cello was once in the hands of "German authorities." I'm guessing that the "Anonymous" owner was Gustav Bloch-Bauer.

The German authorities are only known to have had one Stradivarius cello in their possession, and that would be this cello. If there are any others I doubt that its whereabouts are known today.

I can't find the exact dates of its past owners but I'm going to keep looking. The website on which I found that last bit of information is not giving me the exact chronology of its owners; even if you refresh the page it will reorder the provenances, which is extremely frustrating.

The last Edward I read about had a crazy wife locked in the attic 

There is a 2004 USA Today article that states that after the Allies captured Goering, the jewelry was returned.
