It was purchased by Mouw Diamond Cutting in Johannesburg through a partnership with William Goldberg of New York City.

The polishing of the two main diamonds of 137.02 (Big Rose) and 31.48 (Little Rose) ct. was done by David du Plessis (who was also responsible for polishing The Golden Jubilee and was one of the main polishers of the Centenary Diamond), and the 2.11 carats (422 mg) Baby Rose was done by Mike Botha and Willem Joubert.

The Premier Rose collection ranks among the finest polished gems in the world and became the benchmark in symmetry and proportions for large fancy cut diamonds.

The diamond did not display a definite crystallographic habit and was often incorrectly referred to as a 'cleavage piece'.

The morphology of this diamond was due to plastic deformation during the eruption phase of the kimberlite.
