On the occasion of Queen Elizabeth II's coronation in 1953, the President and the People of Brazil gifted the Queen with a diamond necklace with very large aquamarines and a matching pair of earrings. Later they also gave her a matching bracelet. Queen Elizabeth ordered the royal jeweler, Gerard, to complete the set with a tiara in 1957. The center stone of this tiara was originally the pendant of the necklace. It is larger and more beautiful than any of the other aquamarines in this set. The original design of the tiara included three upright rectangular stones which were detachable for use as brooches. They were mounted on a simple platinum band. In 1971 the piee was adapted to include four fan-shaped ornaments taken from another small tiara given to the queen by the governor of Sao Paulo in 1968.
