That choker returned to HM on Diana's death - it was on exhibition at Buckingham Palace with other jewels as part of the evening gowns exhibition. In all probability it will not be worn for some years to come. The Queen seems to prefer the longer necklace with it's negligee drops, and I can't see Camilla borrowing that choker as it is a fairly small necklace - it was snug even on Diana.

Camilla seems to be happiest wearing treasures from the jewel caskets of the late Queen Mother or pieces which have no obvious royal connections (apart from a few bits that were once Alice Keppel's) I'm sure she has the sense to stay away from wearing anything directly connected to Diana.
