On April 4, 1911, a remarkable collection of British tiaras went on display at Cartier in London.
In 1910, Prince Francis of Teck, brother of Queen Mary, suddenly died. His family set up the Prince Francis of Teck Memorial Fund to raise money for the Middlesex Hospital in his honor.
To benefit the memorial fund, Prince Francis's brother and sister-in-law, Prince Alexander and Princess Alice, suggested that an exhibition of royal tiaras could be mounted in London. The sales from the tickets would go toward the memorial fund. All of the tiaras and jewels on display had recently been refurbished for wear at the upcoming coronation.
Among the jewels on display was the Teck Ears of Wheat Tiara, which Princess Alice wore for the coronation that June. The diamond ears of wheat originally belonged to her mother-in-law (and Prince Francis's mother), the late Duchess of Teck.
Tiaras were also loaned by the Duchess of Albany, the Duchess of Westminster, the Duchess of Newcastle, the Marchioness of Tweeddale, Lady Gerard, and Lady Newborough. Intriguingly, a set of Belgian royal sapphires was also displayed. One of these pieces was eventually purchased by Queen Elizabeth II.

I’d never heard of the Ears of Wheat; it’s quite intriguing that there are several of them and they get arranged in different ways for different occasions.
