[2][3] Large stones like the Jubilee typically go to museums or end up at high-profile auction houses like Christie's.
Christie's has only auctioned 18 polished pink diamonds larger than 10 carats in its 244-year history.
[4] Originally weighing 12.76 carats (2.552 g), the light pink diamond started its cut in Perth in February 2012[3] by Richard How Kim Kam.
[5] While being cut, the diamond was found to have "one major internal fault line that could not be overcome.
"[6] After it was only roughly formed and polished, and down to 8.01 carats (1.602 g), the diamond was donated to the Melbourne Museum.
