Weighing in at 2.23kg (nearly 5lb), the solid gold St. Edward’s crown (1661) is the heaviest crown in the collection. One of the smallest and lightest is Queen Victoria’s Small Diamond Crown (1870), which she wore with her widow’s veil, is tiny at only 9.4cm (3.7 in) high.
By far the largest object in the Jewel House is the extravagantly decorated silver-gilt Grand Punch Bowl (1830). Over a metre wide, and weighing around 248kg (546lb), it was originally intended as a wine-cooler to hold 144 bottles of wine.
There is so much gold thread in the Coronation Robes that they weigh over 13 kgs (30lbs).
Crowns are made with the most expensive materials available at the time. The Crown of Queen Elizabeth the Queen Mother, made for her coronation in 1937, is the only crown in the collection made of platinum.
The twelfth-century Coronation Spoon is the oldest object in the collection. It survived the destruction of the medieval and Tudor crown jewels in 1649, following the Civil War.
