Incredible discovery, thank you very much Erik. Quite sad to find out about these secret auctions, specially after the 2006 auction being cancelled and the Grand Duke's press statement on it... This is of course a private matter of the Granducal family, but its really sad they didn't find a way for these jewels to stay in the family, if not in the main branch at least with the late Granduchess descent. Some of the pieces mentioned were new to me, such as the diamond necklace (and the portrait) from Queen Elizabeth of Belgium.
