Apologies to all, but I did not have the energy to do this post last night.
He spotted that Sheikha Amna bint Mohammed Al Thani was wearing the large bow brooch worn so famously & stylishly by Princess Marina, Duchess of Kent.
I openly acknowledge that I would not have spotted it. What a wonderful knowledge of jewels RDavid has!!
I think this is one of the most exciting finds in recent years.
Many thanks to The Royal Watcher for identifying the lady wearing the brooch -- a wonderful knowledge of who is who in the royal world.
I hope that the images below are self explanatory.
One thing is not in the imagery. I had always heard that the provenance commenced with the Grand Duchess Maria Pavlova who gave it to her daughter, Elena. The Beaumonde, on her blog, noted an item from Cecil Beaton who recorded that Princess Marina had told him that the brooch was a wedding gift to Grand Duchess Elena from the last Czar, Nicholas II.
