The good Duchess seems to be on everyone's mind these days.
I too have been updating my notes on her jewelery and your posts, Beth, Joye, Arthur and Franck are very timely for me. Thanks for the great pictures.
I have one other necklace of a more casual nature that I have noticed HRH wear as well. (There are also some more casual pearls for which I will make a new thread)
I assume that this is from her private collection - but if anyone knows otherwsie, I'd be greatful.
