This is quite fascinating Franck, I am almost certain QA was also in receipt of a Faberge watch of a similar look, I remember seeing it on a documentary where it touched on the well kept Faberge collection of QA and I believe to some extent Prince Charles. I wonder if the the other jewels PA the PR wears are also from the collection of QM or maybe QA or is it a personal set as the picture is a taken with her granny, the late QEQM. I am a firm believer that their lies in the vaults many unseen and unworn jewels stemming right away back to QV and by thus all the subsequent Queens consorts. But the Queen is such a conscious and private individual, we will never see a full quarter of what lies beyond those vaults.

Regards,

Dave.
