Crowning Achievements: The World's Most Beautiful Tiaras

Royal Tiara of Malaysia
Her Majesty Seri Paduka Baginda Raja Permaisuri Agong believes in versatility: her tiara can be taken apart and worn as a locket and several brooches. Known as the Gandik Diraja, or royal tiara, it has a platinum design that unfurls in the awan larat (extending clouds) style. Jewelers crafted it from platinum, encrusted it with diamonds and placed a large crescent and star at its center.
