Queen Elizabeth might have had access to more glittering tiaras than her little sister, but one of Princess Margaret's headpieces is now at the center of an incredible mystery. After many assumed it was lost forever, the first tiara Margaret ever wore appeared on the head of a Malaysian royal bride at her recent wedding.
The Cartier tiara in question is known as Queen Mary's Diamond Lozenge Bandeau and was commissioned by Queen Mary (Queen Elizabeth's grandmother) and worn during the 1930s before being passed on to Princess Margaret. When the princess wore a tiara for the first time in 1948, this was the piece she chose, but it was last seen in 1965, according to Saad Salman of The Royal Watcher.
