The present St Edward's Crown contains much of the crown made in 1661 for the coronation of King Charles II. The crown is made of gold. It weighs 71oz 14dwt. It was set with hired stones for the coronations and then reset with imitations for display purposes. In 1911 it was fitted with 444 semi-precious stones. The crown frame dates to 1661 but it is possible that it (or parts of it) were constructed from a pre-Restoration crown. Materials used include gold, silver, platinum, enamel, tourmalines, topazes, rubies, amethysts, sapphires, garnet, peridot, zircons, spinel, aquamarines, velvet, and ermine.
