Where did Anne Boleyn’s B necklace go?

Some of Anne's pieces of jewellery - including her B necklace, A necklace and AB brooch - were passed on to her daughter Elizabeth, while others are thought to have been reclaimed by the crown and sold, or recut and used by Jane Seymour. Some people have suggested that the pearls from Anne's necklace are in the crown of Elizabeth II but I've been unable to find actual evidence of this claim. Others think that the jewels were sold and may have ended up belonging to members of the French aristicracy. Again, I cannot find any conclusive answers about what happened to them and I can only presume that they are lost.
