I read in one of these wonderfuld boards, that the blue saphire clasp on Princess Dianas pearlnecklace, might come from Mrs. Greville. It was formerly a brooch and a wedding gift to princess Diana from QEQM. She has as far as I know, only worn it after WW2. And not before.
Again, could posters please name the jewel in the subject heading. Hopefully, that will stop confusion.
