The Crown of Queen Elizabeth The Queen Mother, also known as The Queen Mother's Crown, is the crown made for Queen Elizabeth, the wife of King George VI, to wear at their coronation in 1937 and State Openings of Parliament during her husband's reign. The crown was made by Garrard & Co., the Crown Jeweller at the time, and is modelled partly on the design of Queen Mary's Crown, though it differs by having four half-arches instead of eight. As with Queen Mary's Crown, its arches are detachable at the crosses pattée, allowing it to be worn as a circlet or open crown. It is the only crown for a British king or queen to be made of platinum.
