The brooch was of gold, black opals and diamonds in the shape of Australian gum blossoms. The spray is 3 inches long and 1 1/2 inches wide. The brooch has six blossoms, each of which is of Australian black opals. The leaves of the spray are made of 18 carat Australian gold. The stems have diamond dew drops.
Another newspaper reported that it was designed by a Sydney jeweller and that the three gum leaves were joined by a diamond bar.
