The George IV State Diadem, officially the Diamond Diadem, is a type of crown that was made in 1820 for King George IV. The diadem is worn by queens and queens consort in procession to coronations and State Openings of Parliament. The piece of jewellery has been featured in paintings and on stamps and currency. It can be seen in the Queen's Gallery at Buckingham Palace.

The Coronation Necklace was Made for Queen Victoria in 1858 by Garrard & Co., it is 38 cm (15 in) long and consists of 25 cushion diamonds and the 22-carat (4.4 g) Lahore Diamond as a pendant. It has been used together with the Coronation Earrings by queens regnant and consort at every coronation since 1901.

Platypus (Ornithorhynchus anatinus) and the numeral 20.

The platypus (Ornithorhynchus anatinus), also known as the duck-billed platypus, is a semiaquatic egg-laying mammal endemic to eastern Australia, including Tasmania. Together with the four species of echidna, it is one of the five extant species of monotremes, the only mammals that lay eggs instead of giving birth. The animal is the sole living representative of its family (Ornithorhynchidae) and genus (Ornithorhynchus), though a number of related species have been found in the fossil record. The unique features of the platypus make it an important subject in the study of evolutionary biology and a recognisable and iconic symbol of Australia.
