During the 1954 Commonwealth tour The Queen’s State Gift from the Government and People of Australia was this diamond brooch in the form of a spray of wattle. It was designed and made by the Budapest born jeweller Paul Schneller and commissioned by William Drummond & Co. of Melbourne. The yellow diamonds, representing the Australian wattle, are backed by blue-white diamonds in the form of mimosa leaves. The brooch also incorporates diamonds in the form of the blossom of the tea tree with, at the centre, a large white diamond. The Queen wore the brooch on several occasions throughout her Australian visit, including a visit to Flemington Races in Melbourne.
