This brooch is in the form of a spray of wattle, the national flower of Australia, mimosa leaves and tea-tree blossoms. It was presented to The Queen in 1954 as she toured Australia after her Coronation. The brooch has yellow diamonds on the wattle spray, and clear diamonds create the remainder of the flowers.
The piece was a gift from the people and government of Australia at a banquet in Canberra, and was designed and made by Paul Schneller, commissioned by William Drummond & Co. The Queen regularly wears this piece, so it seems to be a favourite of hers.
