Thanks Franck for returning this notation to the board. If indeed the necklace is from the collection of QM it signifies that the PR has some of the most important and valuable jewels in her collection which may have been redesigned for her taste and the modern times. I wonder if the bulk of her collection will return to the mainstream royal line on her passing or auctioned as was the case with the last two Princess Royals? Jewels such as the late Queen Mother's aquamarine tiara, the massive geometric shaped one from the legacy of Margaret Greville, and Prince Phillip's mother's tiara as well as the said necklace in the above captioned topic or the lattice diamond necklace spoken of previously.

Regards,

Dave.
