How beautiful Lady Chomondeley must have looked in those sapphires!
She was apparently quite the jewel lover. In her memoirs Wait for Me!, the Dowager Duchess of Devonshire writes glowingly of the Marchioness of Cholmondeley and states:
Sybil came to Chatsworth to shoot, complete with loader, guns and heavy luggage. She went up to change for dinner but could not find her jewel box. There was a frantic search. Where could it be? It transpired that the box was so big and heavy that the pantry staff had mistaken it for her cartridge case and taken it to the gunroom.
