Crown of Queen Mary
The Crown of Queen Mary is the consort crown made for Queen Mary, wife of George V, in 1911.
Mary bought the Art Deco-inspired crown from Garrard & Co. herself, and hoped that it would be worn by future queens consort. It is unusual for a British crown due to having eight half-arches instead of the traditional two arches. It is tall and weighs.
The silver-gilt crown has around 2,200 rose-cut and brilliant-cut diamonds, and originally contained the Koh-i-Noor diamond, as well as the Cullinan III and Cullinan IV. In 1914, they were all replaced with crystal models, and the arches were made detachable so that it could be worn as a circlet or open crown. Mary wore it like this after George V died in 1936.
Since Queen Mary died in 1953, the crown has not been worn. It is on display with the other Crown Jewels at the Tower of London.
