HM Queen Mary wearing Empress Marie Feodorovna's sapphire and diamond bandeau (later worn by HRH princess Margaret), a pair of pearl earrings, Empress Marie Feodorovna's pearl and sapphire choker (now worn by HRH Princess Anne, the Princess royal), and two other pearl necklaces. The bandeau hasn't been seen for decades, but most people think it's still in the royal collection.
